7/10 = x/12 which mean you need to multiply each side by 12 to find x. So the answer would be X= 8.4
Answer:
acute
Step-by-step explanation:
because it is 90 degree
M/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2
m=22.5
