4(2)+2= 10
Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Using ΔAHC , then
∠ACH = 180 - (2x + 100) = 180 - 2x - 100 = 80 - 2x
∠ECD = ∠ACB ( vertical angles are congruent ), thus
∠ECD = ∠ACH + ∠HCB, that is
3x = 80 - 2x + x
3x = 80 - x ( add x to both sides )
4x = 80 ( divide both sides by 4 )
x = 20
Answer:
60 gallons
Step-by-step explanation:
so he enlarged it by three so it would be 24by30
because of that, you have to multiply 20g by 3 also
that gives you 60 gallons
Answer:
Step-by-step explanation:
BD=BL(given)
so ∠BLD=∠BDL=3x
90+∠GBD+30=180
∠GBD=180-120=60°
Also ∠GBD=∠BLD (given)
so ∠BDL=60°
3x=60
x=20°
