Hello!
The angles are supplementary meaning they add to 180°
a + 2a + 3 = 180
Combine like terms
3a + 3 = 180
Subtract 3 from both sides
3a = 177
Divide both sides by 3
a = 59
the answer is 59°
Hope this helps!
Formula for the perimeter of a rectangle = 2(L + W).
let the width be x
length = 2 + 2x
substitute respectively
52 = 2(2 + 2x + x)
52 = 2 (2 + 3x)
52 = 4 + 6x
52 - 4 = 6x
48 = 6x
divide both sides by 6
48/6 = 6x/6
8 = x
width = 8
length = 2 + 2x = 2 + 2(8) = 2 + 16 = 18
the answer is D because it is the only answer that was clearly defined in the question.
Hope this helps! if it didn't, let me know in the comments! have a great day!
If this is your equation, then:
(37-26)² - (6÷-32÷2²) - (4²-13)
(11²) - (-3/64) - (3)
(121) - (-3/64) - (3)
7555/64
Answer:
p = 1
Step-by-step explanation:
Δ JKH ≅ Δ JIH
therefore KJ corresponds with IJ so you can set both sides equal to each other
10p = p+9
9p = 9
p = 1
