# How can I find the two smaller angles in a triangle with sides of 7 in., 7 in., and 13 in.?

I would like to know the steps of how to get the answer to my question, I don't want just the answer, because I want to be able to also do it on my own in the future. My problem can be solved by using the Law of Cosines. Thank you for whoever is able to answer my question, much appreciated :)

### find the area of a triangle that the sides are 12cm, 8cm and 6cm.

find the area of a triangle that the sides are 12cm, 8cm and 6cm. Layout the triangle with point A at the origin, point B 8cm to the right, and point C somewhere above, 6cm from B and 12cm from the origin. If this were a right-triangle, the hypotenuse would be 10cm, but in this triangle, what would

### How do you calculate volume of a cylinder with ends of different diameter?

A cylinder with different end diameters is a conical cylinder. This means you find the volume of the cylinder by subtracting the volume of a cone from the volume of a larger cone where the smaller cone forms the top section of the larger cone. If you know the two diameters, you can work out the heig

### how to find perimeter of a joint figure

To find the perimeter of a joint figure first find out what simpler figures the whole figures is made of. For example, two right-angled triangles and a rectangle all of equal height can be joined together to make a trapezium, or trapezoid. You then need to identify the common edges, because these wi

### What is the missing step?

We're looking at the smaller triangle at the top of the cone. It's isosceles, so if we drop a perpendicular from apex A onto the base, we split the triangle into two back-to-back right-angled triangles. The angle at A is bisected, so we have A/2. The tangent of A/2 is half the base, which repre

### The pythagorean theorem of this problem x^2+(2x+6)^2=(2x+4)^2

Pythagoras' theorem relates the lengths of the sides of a right-angled triangle: a^2+b^2=c^2 where c, the hypotenuse, is the longest side. In your question 2x+6 is the longest side, so there could be no solution, since the the sum of the two squares of the sides on the left-hand side must be bi

### equilateral math equation help

The side of the square is the square root of its area=sqrt(16)=4. The area of the triangle is half the base times the height. So we need the height of the equilateral triangle. The perpendicular from vertex E bisects AD and the angle AED. The equilateral triangle now consists of two back to back rig

### What are the equal lengths of the remaining 2 sides of the triangle?

Triangle with base line of 6 metres, connecting to 2 equal sides with angles of 10 degrees at the connections. What are the lengths of the remaining 2 sides? To find the hypotenuse of a right triangle, we use the formula c^2 = a^2 + b^2. That is derived from the general forumula c^2 = a^2 + b^2 - (

### Describe the possible values of x on a triangle, if one side's value is 5, 7, and 2x-2.

If the triangle is right-angled, then we can find two solutions before continuing to find others. If 2x-2 is not the hypotenuse, then 7 must be, because it's the longer of the two known sides: 49=25+4(x-1)^2, so (x-1)^2=6 and x=1+sqrt(6). If 2x-2 is the hypotenuse, then: 4(x-1)^2=49+25=74, so x-1=sq

### what are the properties of the quadrilateral whose vertices are the center of the squares?

The quadrilateral so formed is a rhombus (a parallelogram in which all the sides are of equal length). The interior angles of the rhombus are 90+x and 90-x where x is the angle of the parallelogram and where 90+x are the measures of opposite angles of the rhombus. The adjacent angles add up to
