Answer:
<h2>D. y - 5 = 2/3(x + 3)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
We have the slope 2/3 an the point (-3, 5). Substitute:
Answer:
L = 22 ft
Step-by-step explanation:
Let L and W represent the length and width respectively.
L = 4W, or W = L/4. Use W = L/4 because we want to solve for W, not for L.
Area of a rectangle: A = L · W
Here, A = L · L/4 = 121 ft²
Mult. both terms by 4 removes the fraction:
L² = 484
Finding the square root of this result: L = 22
The length of the rect. is 22 ft.
Answer:
248
Step-by-step explanation:
A + B = 180 -EQ 1
A + C =180 -EQ 2
B =124
BY EQ1 :
A = 180 - 124 =56
C = 180 -56 =124
B + C = 124+124
=248
Since ∝ < β you can throw out answers C and D. Using the relationship of sine and cosine being complementary angles you can plug in the two smallest values. Out of those two for 13° you get sin18°=cos72° and 13°+72°=90°, meaning these two angles are complementary.
