Answer:
x = - 7, x = - 1
Step-by-step explanation:
Given
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = 7 and 7 + 1 = 8 , then
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1
Answer:
look at the picture above
Answer: The measure of m∠2=38°
Step-by-step explanation:
Since we have given that
∠1 and ∠2 are complementary adjacent angles.
And, m∠1=52°
As we know that the rule of "Complementary angles":

Hence, m∠2=38° .
