Answer:
x=10
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
7x-3 + 12x-7 = 180
Combine like terms
19x-10 = 180
Add 10 to each side
19x-10+10 = 180+10
19x = 190
Divide by 19
19x/19 = 190/19
x= 10
Answer:
15
Step-by-step explanation:
hypotenuse (h) = 25
perpendicular (p) = 20
base (b) = ?
we know by using Pythagoras theorem we get
b = √h² - p²
= √25² - 20²
= √225
= 15
Answer:
12
Step-by-step explanation:
24/x = x/6
x^2 =24*6 = 144
x=12
A I think this is the answer but I’m not sure
