Really hope this helps, if you need more help I may be able to go more in depth
Answer:
I have provided an explanation on the attached picture. Good Luck.
2x+7x= 180
9x=180
x=20
Plug the x value in to both expressions
2(20)=40
7(20)=140
Final answer: 40 degrees, 140 degrees
Answer:
yes, corresponding angles are congruent
Step-by-step explanation:
Answer:
19.5m
Step-by-step explanation:
Use the Pythagorean theorem.
a^2 + b^2 = c^2
The longest side, 35m, is c and the base of the triangle, 29m, is b.
a^2 + 29^2 = 35^2
Simplify.
a^2 + 841 = 1225
Get a by itself by adding -841 to both sides to cancel out the 841.
a^2 = 384
Find the square root of both sides to get rid of the exponent.
square root of 384 = ~19.5959
a = 19.5
