Well, split it into 3 shapes

21 x 10 = 210

3 x 6 = 18

2 x 6 = 12

210 + 18 + 12 = 240 square cm

imahe for more context

Create and answer your

Step-by-step explanation:

$\frac{20}{48} \times \frac{80}{44}$

Divide the fraction with 4

$\frac{20÷4}{48÷4} \times \frac{80÷4}{44÷4} = \frac{5}{12} \times \frac{20}{11}$

Reduce the number with factor 4

$\frac{5}{12÷4} \times \frac{20÷4}{11} = \frac{5}{3} \times \frac{5}{11}$

Multiply the fractions

$\frac{5 \times 5}{3 \times 11} = \frac{25}{33}$

$\boxed{\green{= \frac{25}{33} = 0.75}}$

angle EFG and angle GFH are a linear pair, m angle GFH= 2n+38 and m angle GFH=2n+38. what are m angle EFG and m angle GFH

motikmotik

Answer:

Part 1) m∠EFG=94°

Part 2) m∠GFH=86°

Step-by-step explanation:

we know that

m∠EFG+m∠GFH=180° -----> by linear pair (given problem)

we have

m∠EFG=3n+22

m∠GFH=2n+38

substitute the values

(3n+22)°+(2n+38)°=180°

Solve for n

(5n+60)=180

5n=180-60

5n=120

n=24

Find the measure of angle EFG

m∠EFG=3n+22

substitute the value of n

m∠EFG=3(24)+22=94°

Find the measure of angle GFH

m∠GFH=2n+38

substitute the value of n

m∠GFH=2(24)+38=86°
