Answer:
54
Step-by-step explanation:
81*36/54
SA=2(LW+LH+WH)
SA=94
L=3
W=4
94=2(3*4+3H+4H)
divide both sides by 2
47=3*4+3H+4H
47=12+7H
minus 12 both sides
35=7H
divide oth sides by 7
5=H

Answer:
x=10
Step-by-step explanation:
The 3 angles of a triangle add to 180
4x+60+80 = 180
Combine like terms
4x+140 =180
Subtract 140 from each side
4x+140-140=180-140
4x = 40
Divide by 4
4x/4 = 40/4
x = 10
