About 172 centimeters tall.
Since he is about 3/4 his average adult height, you simply divide his current height by .75
129/.75 = 172
a linear angle = 180 degrees
180-67 = 113
angle 1 = 113 degrees
Answer:
Miles in 10 gallons = 195
Miles in 1 gallon = 195/10 = <u>1</u><u>9</u><u>.</u><u>5</u>
Miles in 18 gallons = 19.5 × 18 = <u>3</u><u>5</u><u>1</u><u> </u><u>miles</u><u>.</u>
X=113
The angle inside the triangle by the 53 is also 53.
We know triangles have 180 degrees so the other angle is 180-53-60=67
X is the supplementary angle to the 67 so x=113
