Answer:
76cm^2
Step-by-step explanation:
Separate the shape into two different rectangles. Then add the area of the rectangles together.
4 x 4 = 16
6 x 10 = 60
16 + 60 = 76
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA =
cosA = -0.275
A =
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.

Answer:
43.5 cm² and 112 cm²
Step-by-step explanation:
Here the instructions aren't given what to do. So I am finding the area of the ∆s .
<u>Area </u><u>of</u><u> </u><u>first </u><u>∆</u><u> </u><u>:</u><u>-</u><u> </u>
- A = 1/2 * b * h
- A = 1/2 * 14.5 cm * 6cm
- A = 3 × 14.5 cm²
- A = 43.5 cm²
<u>Area </u><u>of</u><u> </u><u>second</u><u> </u><u>∆</u><u> </u><u>:</u><u>-</u><u> </u>
- A = 1/2 * ( sum of || sides) * h
- A = 1/2 * ( 9 cm + 19cm) * 8cm
- A = 4cm * 28cm
- A = 112 cm²
