Answer:
x = 60°
Step-by-step explanation:
This is an equilateral triangle. All angles of this triangle are congruent and have a measure of 60°.
Other method.
We know: the sum of the measures of the angles of the triangle is equal to 180 °.
Therefore we have the equation:
x + x + x = 180°
3x = 180° <em>divide both sides by 3</em>
x = 60°
Answer:
20..... 1/10
Step-by-step explanation:4x5 equals twenty
2/20 divided by 2 is 1/10
Answer: 6 Kilometers
Step-by-step explanation:
1 kilometer = 1000 meters
6 kilometers=6000 meters
6 x 1000=6000
An complementary angle = 90°
one of the angles is twice as large as the smaller one
let the larger angle be x, and the smaller = y
x = 2(y)
x + y = 90
Plug in 2y for x
2y + y = 90
simplify, combine like terms
2y + y = 90
3y = 90
isolate the y, divide 3 from both sides
3y/3 = 90/3
y = 90/3
y = 30
plug in 30 for y in the equation x + y = 90
x + (30) = 90
isolate the x, subtract 30 from both sides
x + 30 (-30) = 90 (-30)
x = 90 - 30
x = 60°
The measurement of the larger angle is 60°
hope this helps
