Answer:
2/4 +6/8 =5/4
Step-by-step explanation:
Use Pythagorean theorem.
a^2 + b^2 = c^2
D.
21^2 + 72^2 = 75^2
441 + 5184 = 5625
Answer:
x=43°
Step-by-step explanation:
The angles are adjacent and create a straight line so their sum is 180°.
(x+6)°+(3x+2)°=180°
x°+6°+3x°+2°=180°
4x°+8°=180°
4x°=172°
x=43°
Answer:
m<BCA+m<BCD=180
Step-by-step explanation:
supplementary means that the angle measures add up to 180°, if you are using the definition of supplementary angles AND you have had a statement saying that two angles are supplementary, ALWAYS follow it with the sum of the measures of those angles equal 180 :)
