Answer:

m∠4 = 55°

Step-by-step explanation:

From the figure attached,

m∠DBC = m∠BCA + m∠BAC [Exterior angle of a triangle equals the sum of the remote interior angles]

m∠4 = 30° + 25° = 55°

Therefore, m∠4 = 55° will be the answer.

Step-by-step explanation:

So the answer for 33+45+78 is 156.

If you want to check that, you can use inverse operations, so subtract.

156-78=78. (Check 78)

78-45=33 (Check 45 and 33)

Well, now it's checked because we used all the factors of the equation!

Find the area of the composite figure.

dmitriy555 [2]

Answer:

B. $200.5 \: {m}^{2}$

Step-by-step explanation:

Area of the composite figure = Area of square with side length 12 m + Area of semicircle with radius (12/2= 6) 6 m

$= {(12)}^{2} + \frac{1}{2} \pi {r}^{2} \\ \\ = 144 + \frac{1}{2} \times 3.14(6)^{2} \\ \\ = 144 + \frac{1}{2} \times 3.14 \times 36 \\ \\ = 144 + 56.52 \\ \\ = 200.52 \: {m}^{2} \\ \\ \approx \: 200.5 \: {m}^{2}$
