Hope it helped <span>y = x/5 + 12/5 </span>
Answer:
x = 20 (degrees)
y = 70 (degrees)
Step-by-step explanation:
The angle adjacent to the one labeled 40° is supplementary, so it would measure 140°. And the obtuse triangle is an isosceles, which means that x is half of 180° - 140°, so x = 1/2(40°) = 20°
To find y, subtract 90° and x from 180°
y = 180° - 90° - 20°
y = 70°
Answer:
-0.04x + 1100
Step-by-step explanation:
0.07x + 0.11(10,000-x) open bracket by multiplying by 0.11
= 0.07x + 1100 - 0.11x collect like terms
= 0.07x - 0.11x + 1100
= -0.04x + 1100
