Answer:
a.
b.
Step-by-step explanation:
a. We know that angles in a triangle add up to 180°.
-The right angle triangle in the right triangle has a measure of 90°.
We can therefore equate our angles to 180° and solve for x;
Hence, the angle measure is x=10°
b. Having calculated the value of x from a above as x=10°, we can substitute to find the measures of the two acute angles:
Since, the m∠K is a right angle, it measures 90°
Answer:
See below
Step-by-step explanation:
r/6 <-6 multiply both sides by 6 to get
<u>r < - 36 </u>
<u />
<u> or</u> 4r+2 > 18 subtract 2 from both sides of the equation
4r > 16 divide both sides by 4
<u> r > 4 </u>

Answer:</h2>
18
Step-by-step explanation:
10$ 180$
10 x 18 = 180
so she work 18 hours.
Answer:
Step-by-step explanation:
So 11 times 2=22 so you times 11 times 2 on all sides so the answers is 22
Answer:
b = 10
-2d = -38
x = -1.2
Step-by-step explanation:
b = 10 and x = -1.2 only have one variable. You can divide -2 to both sides for -2d = -38 getting d = 19.
0.1 = 0.1 have no variable meaning that any number can be correct in the equation
1/3 ≠ 1/3 has a cross in the equal sign meaning that there is no correct answer for the equation.
