Answer:

45 units

Step-by-step explanation:

Since both figures are similar, the ratio of their similar sides will be equal to a constant. Hence;

8/10 = 12/EH

8EH = 12 * 10

8EH = 120

EH = 120/8

EH = 15

Perimeter of EFGH = 15 + 10 + 5 + 15 = 45 units

Can anyone please help me what is x

Masja [62]

Step-by-step explanation:

the side on the left of 155 is 180-155 which is 25

the one on top of 120 is 180-120 which is 60 so the one on the right of x is 180-(25+60) which is 95

now the value of x is 180-95 which is 85.

in the second one x=180-100 because the angle on the bottom of x is corresponding to the one that's equal to 100, so x=180-100 which is 80

for the first one x=85

the second one x=80

Fast I need to know what 20/22= x/11

sergij07 [2.7K]

Answer:

To Find => The value of x. in the equation below

$20 \div 22 = x \div 11$

Step-by-step explanation:

We will cross Multiply the digits

=>20 \div 22 = x \div 20

=>We'll cross Multiply

$20 \div 22 = x \div 11 \\ = > 22x = 20 \times 11 \\ = > 22x = 220 \\ = > x = 220 \div 22 \\ = > x = 10$

Hence, 10 is the required answer
