15. In the rhombus shown below, mz1 = 160°. What are the measures of 22 2 points
egoroff_w [7]

Answers:

angle2 = 160 degrees

angle3 = 10 degrees

============================================

Explanation:

The two triangles are congruent. We can prove this using SSS. The upper triangle is a mirrored copy of the lower triangle.

Since angle1 = 160 degrees, this means angle2 = 160 also. This is because the corresponding pieces of congruent triangles match up. Or you could use the second part of the hint which says "Opposite angles in a rhombus are congruent".

Let x be the measure of angle 3. For either isosceles triangle, it has congruent base angles measured x degrees. They add to the 160 degrees mentioned earlier to get a total of 180.

160+x+x = 180

2x+160 = 180

2x = 180-160

2x = 20

x = 20/2

x = 10

Angle 3 is 10 degrees.

Hello!

You have to find the area of the prism and the pyramid

rectangular prism is lwh

Put in the values you know

15 * 5 * 7 = 525

For a prism you use

\frac{lwh}{3}

Put in the values you know

\frac{15 * 5 *13 }{3}

Multiply

975/3

Divide

325

Add the values you know

325 + 525 = 850

The answer is D)850cm^{3}

Hope this helps!
