1½–¾ what is the answer to this fraction ​

Step-by-step explanation:

~Convert the mixed numbers into improper fractions

~Then find the LCD (Least Common Denominator) and combine

GL.

B(3x-4) and D(2x-6)

first find the value of x.

3x-4 + 2x-6=90

3x+2x-4-6=90

5x-10=90

5x=90+10

5x=100 divid 5 both sides with.

u will get

x=20

then now find the angles of B and D.

B (3x-4) +D (2x-6)=90

so for angle of B° is.

3x-4=90.

B°+3(20)-4=90

B°+60-4=90

B°+56=90

B°=90-56

B=34° ANs.

for angle D°

D°2x-6=90

D°+2(20)-6=90

D°+40-6=90

D°+36=90

D°=90-36

D=56° ANs.
