If the larger angle is x and the smaller angle is y, y=(1/2)x+30 since it's 30 more than 1/2 of it. In addition, x+y=180 since they are supplementary. Plugging y=(1/2)x+30 into that, we get x+x/2+30=180=1.5x+30. Subtracting 30 from both sides, we get 1.5x=150. Next, we can divide both sides by 1.5 to get x=100 and y=(1/2)*100+30=50+30=80
I got this on the calculator.
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<u><em>10=3x-8</em></u>
<u><em>always remember to flip the equation</em></u>
<u><em>3x-8=10</em></u>
<u><em>Add 8 to both sides</em></u>
<u><em>3x-8(+8)=10(+8)</em></u>
<u><em>3x=18</em></u>
<u><em>Divide both sides by 3</em></u>
<u><em>3x/3=18/3</em></u>
<u><em>x=6</em></u>
Answer:
8/15
Step-by-step explanation:
In a right triangle, where B is an acute angle, the tan B is equal to the measure of the side opposite B divided by the measure of the shorter side at B
tanB = 16/30 = 8/15
The answer would be D) because its true and the difference is -0.2.
