Answer:
A : 4x+5x=180
Step-by-step explanation:
They form a linear pair which equals 180.
Answer:
All of them except B
Step-by-step explanation:
Bisecting is splitting a line in half
Parallel lines never touch each other
Intersecting lines intersect
Corresponding lines are 2 parallel lines with a line that is going through them
Winter
Winter comes after fall in the pattern as we see already. Because this is true, winter is next.
Answer:
m∠N = 51°
m∠M = 31°
m∠O = 98°
Step-by-step explanation:
It is given that ΔMNO is an isosceles triangle with base NM.
m∠N = (4x + 7)° and m∠M = (2x + 29)°
By the property of an isosceles triangle,
Two legs of an isosceles triangle are equal in measure.
ON ≅ OM
And angles opposite to these equal sides measure the same.
m∠N = m∠M
(4x + 7) = (2x + 29)
4x - 2x = 29 - 7
2x = 22
x = 11
m∠N = (4x + 7)° = 51°
m∠M = (2x + 9)° = 31°
m∠O = 180° - (m∠N + m∠M)
= 180° - (51° + 31°)
= 180° - 82°
= 98°
(2x-4)(x+5) expand with indicated multiplication
2x^2+10x-4x-20
2x^2+6x-20
