Hey there! I'm happy to help!
If angles are complementary, they add up to 90 degrees.
This gives us this system of equations.
J=K-18
J+K=90
We plug the value of J into the second equation to solve for K.
K-18+K=90
We combine like terms.
2K-18=90
Add 18 to both sides.
2K=108
Divide both sides by 2.
K=54
J is 18 less than K.
54-18=36
Therefore, angle J is 36 degrees and angle K is 54 degrees.
Have a wonderful day! :D
Answer:
x = 20°
Step-by-step explanation:
An equilateral triangle has three equal angles of 60° each.
Since ∆BCD is an equilateral triangle, it follows that:
<CBD = <BCD = <CDB = 60°
m<ACD = 40° + <BCD
m<ACD = 40° + 60° (substitution)
m<ACD = 100°
x + m<ACD + CDB = 180° (sum of triangle)
x + 100° + 60° = 180° (substitution)
x + 160 = 180
Subtract 160 from each side
x = 180 - 160
x = 20°
