What are the three angle measures in the triangle shown below

sergeinik [125]

B. 31°, 43°, 106°
since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B

80 km is 9% of what distance??

Karolina [17]

Answer:

80 km is 9% of 888.89 km.

Step-by-step explanation:

We know that:

80 km = 9%

Work:

80/9 km = 1%
=> 80/9 x 100 = 100%
=> 8000/9 = 100%
=> 888.89 km = 100% (Rounded to nearest hundredth)

Hence, 80 km is 9% of 888.89 km.
