Find the area of triangle abc. round your answer to the nearest tenth. m∠a= 52°, a = 9.71, c = 9.33
a. 44.5 c. 49.4 b. 33.6 d. 77.1

The area of the Δ = 44.5 units² ⇒ answer (a)

Step-by-step explanation:

∵ a = 9.71 , c = 9.33 , m∠A = 52°

To find the area of the triangle we must have:

m∠B or b

By using sin Rule:

∵ a/sin∠A = c/sin∠C

∴ 9.71/sin52 = 9.33/sinC

∴ sinC = (9.33 × sin52) ÷ 9.71 = 0.757172

∴ m∠C = 49.2°

∴ m∠B = 180 - 52 - 49.2 = 78.8°

∵ A the Δ = 1/2 × a × c × sinB

∴ A = 1/2 × 9.71 × 9.33 × sin78.8 = 44.5 units² ⇒ answer (a)

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
