Answer:

m < 2 = 137°

m < 4 = 137°

Step-by-step explanation:

Given that m < 7 = 43°, we can say that it has the same measure as < 3 because they are corresponding angles. Thus, we can establish that m < 3 = 43°.

We can use m < 3 = 43° to find m < 4, as they are supplementary angles that have a sum of 180°.

Therefore:

m < 3 + m < 4 = 180°

Rearrange the formula to isolate m < 4:

m < 4 = 180° - m < 3

Substitute the value of m < 3 into the rearranged formula:

m < 4 = 180° - m < 3

m < 4 = 180° - 43°

m < 4 = 137°

Therefore, m < 4 = 137°.

< 2 and < 4 also have the same measure because they are vertical angles.  Two angles are vertical angles if they are opposite angles formed by the intersection of two lines.  

Hence, m < 2 = 137°

PLEASE HELP
SVETLANKA909090 [29]

Answer:

f(x) = 2(x + 4)² - 2

Step-by-step explanation:

Equation of quadratic function whose vertex is (h, k),

f(x) = a(x - h)² + k

Equation of the function with vertex (-4, -2) shown in the graph will be,

f(x) = a(x + 4)² - 2

This graph is passing through a point (-6, 6) also,

6 = a(-6 + 4)² - 2

6 + 2 = a(-2)²

a = \frac{8}{4} = 2

Therefore, quadratic function is f(x) = 2(x + 4)² - 2
