Answer:
45 is the answer
Step-by-step explanation:
first you have to know the sum of interior angle of that pentagon (540)
then add the all angle.
148 + x + 112 + 90 + 3x + 10 = 540.
or, 360 + 4x = 540
or, 4x = 540 - 360
or, 4x = 180
or, x = 180/4
or, x = 45
hope it will help you☺✌
Answer:
C) 16
Step-by-step explanation:

Hey!
------------------------------------------------
-x = -1
This statement shows that y equals -1. Since it doesn't show a table or word problem then we already know that the constant of proportionality is -1. Or if you just have the expression just divide the number by 1. -x/1 = -1!
------------------------------------------------
Thus, -1 is the constant of proportionality!

Answer:
Step-by-step explanation:
Use the formula for the area of a triangle,
Area of a triangle = 
7). Area of the triangle = 
= 74 km²
8). Area of the triangle = 
= 30.8 cm²
9). Area of the triangle = 
= 56 m²
10). Area of the triangle = 
= 42.35 km²
X=Y-7
4X+2Y=62
4(Y-7)+2Y=62
4Y-28+2Y=62
6Y=62+28
6Y=90
Y=90/6
Y=15
Larger number^
X=15-7=8
Smaller number^
PROOF:
4*8+2*15=62
32+30=62
62=62
Hope this helps.
