The first thing you do is cross multiply which is 3/4x=48 (3/4 = 0.75). Therfore you divide each side by .75. The left side cancels out. For the right side you divide 48 by .75 and gives you 64. x=64
8n=90-n
first get the n to one side...
8n^2=90
then divide
n^2=11.25
(i feel like theres one more step but im unsure)
Answer:
∠CGA or ∠DGF
Step-by-step explanation:
Supplementary angles add up 180°
∠CGD + ∠CGA = 180°
∠CGD + ∠DGF = 180°
It looks alright to me but i would check it again see if you missed anything <span />
