Answer:
x=29
Step-by-step explanation:
Answer:
76°
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
52° + 12x + 4 = 22x - 4
52 = 22x - 4 - 12x - 4
52 = 10x - 8 add 8 to both sides
60 = 10x divide both sides by 10
6 = x
The measure of angle F is 12x + 4, replace x with the value we found
m<F 12 × 6 + 4 = 76°
Answer:
12 mph and 16 mph
Step-by-step explanation:
distance = speed * time
56 = s * 2 + (s - 4) * 2
56 = 2s + 2s - 8
56 = 4s - 8
64 = 4s
16 = s
s = 16
s - 4 = 12
The answer is 2 for 5.80 is cheaper for buying 30 t-shirts.
Answer:
x = 9
Step-by-step explanation:
Since you have a equilateral triangle all angles are 60°.
7x - 3 = 60
7x = 60+3
7x = 63
x = 63/7
x = 9
