Answer:
Correct choice is C). mn=ac
Step-by-step explanation:
Given statement is that the first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.
We know that when we factor polynomial of type ,product of both numbers m and n must be same as product of a and c.
Hence correct choice is C). mn=ac
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 =
= 0.84167
Y =
Y = 32.68 ≈ 32.7°
Therefore, measure of angle Y = 32.7°
