Well since the triangle is right angled you know that the given angles sum to 90........(angle sum of a triangle 180, 1 angle = 90) so you can say 3x + 6 + 2x - 1 = 90 or 5x - 5 = 90 now solve for x. the smaller angle will be 2x - 1 so substitute your answer for x and you'll have the measure of the smaller angle. hope that helps
Answer:
112m^3
Step-by-step explanation:
use formula 1/3(lwh)
1/3(6)(8)(7)
112
When multiplying by a number that is 1 with 0's on the end, you move the decimal to the right by how many zeros there are.
Because 10,000 has 5 0's, we move the decimal 5 places to the right.
8.88 => 88800
Answer:
7.) 26
8.) 16
9.) 14
10.) 27
Step-by-step explanation:
1. cos (angle) = adjacent leg / hypotenuse
cos(50) = 10/X
x = 10/cos(50)
x = 15.6 feet
2.
tan(angle) = Opposite leg / adjacent leg
tan(5.5) = 600/x
x = 600/tan(5.5)
x = 6,231.2 feet.
