Answer:
Option C is correct.
Step-by-step explanation:
Given: A rhombus. m∠1 = 40°
To find: m∠2
We know that Rhombus is a parallelogram with all equal sides.
⇒ Opposite sides of the Rhombus are parallel.
Then Diagonal act as a traversal for parallel sides.
So, m∠2 = m∠1 ( Alternate Interior Angles are equal )
m∠2 = 40°
Therefore, Option C is correct.
Answer:
total area = 615 sq. in.
Step-by-step explanation:
There are 4 triangles that make up the lateral area. The base of each triangle is 60/4 = 15 in. and the height of each triangle is 13 in. So, the area of one triangle = .5bh = .5(15)(13) = 97.5. The lateral area = 4(97.5) = 390. The area of the square base is 15(15) = 225. The total area = 390 + 225 = 615 sq. in.
