How would I prove this

Mathematics
1 answer:
Inessa05 [86]3 years ago
7 0

Answer:

∠1 ≅ ∠2 by the Alternate Interior Angles Theorem

m∠3 = 130° due to the Congruent Supplements Theorem

Step-by-step explanation:

The Alternate Interior Angles Theorem State that if two parallel lines are split by a transversal, then the pairs of alternate interior angles are congruent.

In this case, the measure of ∠1 is equal to 180° - m∠3 due to the Congruent Supplements Theorem. So, m∠1 is equal to 50°, which also means m∠2 is also 50°.

Advocard [28]

Answer:

Step-by-step explanation:

i assume x+y=6(1/2)=\frac{13}{2}

\frac{5}{8}=\frac{x}{y}=\frac{x}{\frac{13}{2}-x}=\frac{2x}{13-2x}\\65-10x=16x \\26 x=65\\2x=5\\x=\frac{5}{2}\\y=\frac{13}{2}-\frac{5}{2}=\frac{8}{2}=4

What is the slope of the line?
Vesnalui [34]
It's a flat horizontal line so the slope is 0

Slope = rise/run = 0/run = 0

The "run" can be any number you want as long as it's not 0.

Find the area of the trapazoid for me please :)
Doss [256]

Answer:

A = 14 m^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2) *h  where b is the length of the bases and h is the height

A = 1/2 (2+5) *4

A = 1/2(7)4

A = 14 m^2
