Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
Answer:
12c +9 = Perimeter
Step-by-step explanation:
The perimeter of a triangle is found by adding all the sides
3c+4 + 5c-2 + 4c +7 = Perimeter
Combine like terms
12c +9 = Perimeter
I dotn believe that a pair of angles can be vertical and supplementary. because vertical angles are across from each other, and supplementary angles are two angles next to each other (adjacent) that have a sum of 180. im not sure how to give an example/nonexample.
Answer:
x= 29
Step-by-step explanation:
These angles equal 180° since they are corresponding angles.
So, the equation would be: (2x-10)+(4x+16)= 180.
Step 1- Add common variables.
(2x+4x)+(16-10)= 180
6x+6= 180
Step 2- Subtract 6 to both sides.
6x+6= 180
-6 -6
6x= 174
Step 3- Divide both sides by 6.
<u>6x</u>= <u>174</u>
6 6
x= 29
