Answer:

135

Step-by-step explanation:

Supplementary means both angles equal 180 degrees when combined

180 - 45 = 135

Complementary means both equal 9 degrees when combined

if u think connect the lines of S and it makes and 8 for 180 and C makes 9 for 90

The H.C.F and the LCM of two numbers are 36 and 720 respectively. If one of the numbers is 180, which is the other number. *

lutik1710 [3]

Answer:

let p(x)=180

LCM=720

HCF=36

WE HAVE TO FIND q(x)=?

as we know that

p(x)×q(x)=LCM×HCF

NOW WE HAVE TO FIND q(x)

q(x)=LCM×HCF/p(x)

q(x)=720×36/180

q(x)=25920/180

q(x)=144

i hope this will help you

andreev551 [17]

Please consider the complete question.

A parking lot in the shape of a trapezoid has an area of 12,052.1 square meters. The length of one base is 82.4 meters and the length of the base is 108.6 meters. What is the width of the parking lot

We will use area of trapezoid to formula to solve our given problem.

$\text{Area of trapezoid}=\frac{1}{2}(a+b)\times h$ , where

a and b represents parallel sides of trapezoid,

h = height of trapezoid.

Width of the trapezoid will be equal to height.

Upon substituting our given values in above formula, we will get:

$12,052.1=\frac{1}{2}(82.4+108.6)\times h$

$12,052.1\cdot 2=2\cdot \frac{1}{2}(82.4+108.6)\times h$

$24104.2=(191)\times h$

$\frac{24104.2}{191}=\frac{(191)\times h}{191}$

$126.2=h$

Therefore, the width of the parking lot is 126.2 meters.

What is the surface area in yards squared of the triangular prism shown below?

hichkok12 [17]

Answer:

1,120 yd²

Step-by-step explanation:

Surface area of triangular prism = 2(BA) + P*H

✔️Triangular base area (BA) = ½bh

b = 15 yd

h = 8 yd

Base area (BA) = ½*8*15 = 60 yd²

✔️Perimeter of the base (P) = 17 + 15 + 8 = 40 yd

✔️Height or lenghtbor prism (P) = 25 yd

✔️Surface area = 2(60) + 40*25 = 120 + 1,000 = 1,120 yd²
