I need help with geometry
satela [25.4K]

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☺✌

Y = -x<br><br> What is is the constant of proportionality
Stels [109]

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!

------------------------------------------------

Hope This Helped! Good Luck!

mr_godi [17]

Answer:

Step-by-step explanation:

Use the formula for the area of a triangle,

Area of a triangle = \frac{1}{2}(\text{Base})(\text{Height})

7). Area of the triangle = \frac{1}{2}(20)(7.4)

                                       = 74 km²

8). Area of the triangle = \frac{1}{2}(4)(15.4)

                                     = 30.8 cm²

9). Area of the triangle = \frac{1}{2}(16)(7)

                                      = 56 m²

10). Area of the triangle = \frac{1}{2}(11)(7.7)

                                       = 42.35 km²

One number is 7 less than another. If 4 times the smaller number plus 2 times the larger number is 62, find the two numbers.
Nana76 [90]
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.
