X=7
Explanation:
A triangle equals 180°, and they gave us one length already, and it says the one arm of the triangle is equal to the other so we know that the third angle is going to be the same as the second angle.
180=90+(6x+3)+(6x+3)
Combine like terms
180=96+12x
Subtract 96 from both sides
84=12x
Divide 12 by both sides
7=x
Now check it,
90+(6*7+3)+(6*7+3)
90+(45)+(45) =180
Answer:
m<PXQ Is Acute
m<QXN is Obtuse
Step-by-step explanation:
Acute Angles are lsss than 90⁰
Obtuse Angles are greater than 90⁰
Right angles are exactly 90⁰
Answer:
18
Step-by-step explanation:
Perimeter means the sides add up to 12.
Rectangles have two pairs of equal sides.
2(one side) + 2(another side) = 12
2 (one side + another side) = 12
(one side + another side) = 6
To draw a rectangle with a perimeter of 12 units, the two adjacent sides must add up to 6.
1 + 5
2 + 4
3 + 3
