The area <em>A</em> of a trapezoid with height <em>h</em> and bases <em>b</em>₁ and <em>b</em>₂ is equal to the average of the bases times the height:
<em>A</em> = (<em>b</em>₁ + <em>b</em>₂) <em>h</em> / 2
We're given <em>A</em> = 864, <em>h</em> = 24, and one of the bases has length 30, so
864 = (<em>b</em>₁ + 30) 24 / 2
864 = (<em>b</em>₁ + 30) 12
864 = (<em>b</em>₁ + 30) 12
72 = <em>b</em>₁ + 30
<em>b</em>₁ = 42
Answer:
A
Step-by-step explanation:
-4x-10≤2
-4x≤12 Add 10 on both sides
-x≤3 Divide by 4 on both sides
x≤-3 put a negative on both sides
Hope this helps :D Please mark brainliest if correct :D
Using trigonometry
tan(x)=9/6
use your calculator to find x using tan-1(9/6) and you get 56.3° which is basically the first answer
Answer:
Equivalent equations are algebraic equations that have identical solutions or roots. you can find it by adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation as well as multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
Step-by-step explanation:
125 is part of a supplementary angle so you need to subtract 125 from 180
which is 55
so the angle adjaecent to to the 125 angle is 55 degrees
