Can someone help me!

victus00 [196]

Answer:

m∠A = 48.81°

Step-by-step explanation:

Given triangle is a right triangle and we have to measure ∠A.

Since, opposite side and adjacent sides of angle A has been given

So we will apply tangent rule to get the measure of angle A.

tan(∠A) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(∠A) = $\frac{8}{7}$

∠A = $\text{tan}^{-1}(\frac{8}{7})$

∠A = 48.814

≈ 48.81°

Because ABCD is a rhombus, ΔABC ~ ΔADC.

The length of AC = 4 (the base of ΔABC.
The height of ΔABC = 7 - 1 = 6
The area of ΔABC is
(1/2)*4*6 = 12

Therefore the area of ABCD = 2*12 = 24
