Answer:
x=88, so it is acute.
Step-by-step explanation:
The two known angles are 45 degrees and 47 degrees. We know that in a triangle, the three angles always add up to 180 degrees.
This means that the third angle is 180-(45+47), or 180-92, or 88. So, the third angle is 88 degrees.
Acute triangles are when all the angles are less than 90. Right is when one angle is exactly 90. Obtuse is when one is more than 90. 88, 45, and 47 are all less than 90, so it is an acute triangle.
Answer:
We can conclude that if two parallel lines are cut by a transversal, then the alternate interior angles are congruent.

Answer:
10.63
Step-by-step explanation:
The distance between two points is sqrt((difference between y-values)^2 + (difference between x-values)^2) -->
sqrt(8^2 + 7^2) =
sqrt(64 + 49) =
sqrt( 113) =
10.630145 -->
10.63
Answer:
F=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(6−f)−4=3f−4
(3)(6)+(3)(−f)+−4=3f+−4(Distribute)
18+−3f+−4=3f+−4
(−3f)+(18+−4)=3f−4(Combine Like Terms)
−3f+14=3f−4
−3f+14=3f−4
Step 2: Subtract 3f from both sides.
−3f+14−3f=3f−4−3f
−6f+14=−4
Step 3: Subtract 14 from both sides.
−6f+14−14=−4−14
−6f=−18
Step 4: Divide both sides by -6.
−6f−6=−18−6f=3
Answer:
f=3
