∠ 1 and ∠ 2 are complementary angles, if ∠ 1= 3x+10 and ∠ 2 = 4x-25. Find the measurement of ∠ 1 and ∠ 2

viktelen [127]

Answer:

<1 = 55 degrees and <2 = 35 degrees

Step-by-step explanation:

Sum of complementary angles is 90.

<1 = 3x + 10

<2 = 4x - 25

3x + 10 + 4x - 25 = 90

7x - 15 = 90

7x = 105

x = 15

<1 = 3(15) + 10

<1 = 55

<2 = 4(15) - 25

<2 = 35

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the expression:

$(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1} \\\\This\ can\ be\ simplified\ to:\\\\(\frac{2(2k+1)(k-2)}{(k+2)(k-2)(2k+1)}) \\\\=\frac{2}{k+2}$

The product of the expression $(\frac{4k+2}{k^2-4})* \frac{k-2}{2k+1}$ is the expression $\frac{2}{k+2}$
