Answer:
20
Step-by-step explanation:
From if y=-7 when x=-14 ----> x=2y

Answer: 42.5 m
Step-by-step explanation:
Split the figure into a rectangle and a triangle.
Find the areas of the rectangle and the triangle seperately and add them together.
Rectangle: 7 x 5 = 35
Triangle: 5 x 3/2 = 7.5
35+7.5= 42.5m
3. Congruent, 30 degrees
4. 2x+30+50=180
80+2x=180
x=50
2x=100
5. 3x-13+58=90, so 3x+45=90
3x=45 x=15
3x-13=3(15)-13
=45-13
=32 degrees
The correct answer is d I hope this helps
