Answer:
m∠A = 139°
Step-by-step explanation:
Since knowing that:
Supplementary angles = 180 degree
Thus we put that in both equation:
( 7x - 15 ) + ( 2x - 3 ) = 180
Combine like terms & use inverse operations to find the value of x:
( 7x - 15 ) + ( 2x - 3 ) = 180
9x - 18 = 180
9x - 18 + 18 = 180 + 18
9x = 198
9x/9 = 198/9
x = 22
Hence, Angle A will have a measure of 7x - 15 which means 7 × 22 -15 = 154 - 15 = 139°
m∠A = 139°
The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
m∠ B = 41°
Check Answer by add 139 and 31 which equal 180

Answer:
First statement: Angles 1 and 3 are vertical angles.
First reason: Definition of supplementary
Second Reason: Vertical angles are congruent
Third Reason: Vertical Angles Theorem
Step-by-step explanation:
Hope this helps: Angles that form an X- Type figure are congruent.
Answer:
x = −2
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(−3x+4)+3x−3=−29
Step 1: Simplify both sides of the equation.
−2(−3x+4)+3x−3=−29
(−2)(−3x)+(−2)(4)+3x+−3=−29(Distribute)
6x+−8+3x+−3=−29
(6x+3x)+(−8+−3)=−29(Combine Like Terms)
9x+−11=−29
9x−11=−29
Step 2: Add 11 to both sides.
9x−11+11=−29+11
9x=−18
Step 3: Divide both sides by 9.
9x
/9 = −18
/9
x=−2

Step-by-step explanation:
3/4x + 5/8 = 4x/1
5/8 = 4x/1 - 3/4x
5/8 = 16x^2 - 3/4x
5/8 = 4x - 3/1
5/8 = 4x - 3
Cross multiply
8(4x - 3) = 5
32x - 24 = 5
32x = 5 + 24
32x = 29
X = 29/32
