Well it actually is less than quotient because the number you're dividing by is always smaller than the quotient.

Answer:

Y = 32.7°

Step-by-step explanation:

We will apply the Cosine law in the given triangle XYZ,

x = 90 ft

y = 55 ft

z = 50 ft

We have to find the measure of angle Y.

y² = x² + z² - 2xzCosY

(55)² = (90)² + (50)² - 2(90)(50)cosY

3025 = 8100 + 2500 - 9000.cosY

9000.cosY = 10600 - 3025

cosY = $\frac{7575}{9000}$

= 0.84167

Y = $\text{cos}^{-1}(0.84167)$

Y = 32.68 ≈ 32.7°

Therefore, measure of angle Y = 32.7°

What is 17.70 = 7/2m + 13.50 ?

Fantom [35]

answer: $m = 1.2$

work:

$17.70 = \frac{7}{2} m + 13.50$ | subtract 13.50 and move it over

$4.2 = \frac{7}{2}m$ | divide by 7/2

$1.2 = m$ | final answer
