Hello!
If By = 52 then m<BAY = 26
m<BAC = 90
m<BAC = m<BAY + m<YAC
Substitute the values we know
90 = 26 + m<YAC
Subtract 26 from both sides
64 = m<YAC
The answer is B
Hope this helps!

Answer:
Step-by-step explanation:
1. To find a rational number between two numbers, divide the sum of the number by 2,
(1/4 + 1/2) × 1/2
=> [ (2 + 1)/4] × 1/2
=> 3/4 × 1/2
=> 3/8
3/8 is a rational number between 1/4 and 1/2
3. any positive number is greater than a negative so 1 2 3 4 5 6 7 8 9 and -2

Answer:
x = -21
Step-by-step explanation:
<h2>Words To Algebra:</h2>
Words : Five more than one-third of a number = -2
Algebraic Equation: 5 + (1/3)x = -2
<h2>Isolate x:</h2>
5 + (1/3)x = -2 Subtract 5 from both sides
5 + (1/3)x - 5 = -2 - 5
(1/3)x = -7 Multiply All sides by 3
(1/3)x * 3 = -7 * 3
x = -21
<h2 /><h2>Check:</h2>
5 + (1/3)-21 = -2
5 + -7 = -2
-2 = -2
