Answer: √117
Step-by-step explanation:
Since no diagram present, am assuming hypotenuse AB and right angle C. Let side opp angle B be b, and side opposite angle A be a. Altitude CD is x.
a^2 + b^2 = 22^2 (Pythagorean)
Using Pythag on two smaller triangles,
x^2 + 13^2 = a^2
x^2 + 9^2 = b^2
Substituting in first equation,
x^2 + 13^2 + x^2 + 9^2 = 22^2
x^2 = 117, so x = √117
8.3+12+9.1+7.2= 36.6 divide it by 4 which is the number of factors the answer is 9.15
Each tube costs $2.25
24.95-6.95=18
18/8=2.25
Answer:
x= 30
The angles measure 80 degrees
Step-by-step explanation:
The two angles are corresponding angles and, when the lines are parallel, corresponding angles are equal.
2x+20 = 3x-10
Subtract 2x from each side
2x+20-2x = 3x-10-2x
20 = x-10
Add 10 from each side
20+10=x-10+10
30 = x
2x+20 = 2(30) +20 = 60+20 = 80
