Answer:
Linear pair is a pair of adjacent angles formed when two lines intersect.
so, 
and 
are linear pairs.
Linear pairs are always supplementary.
therefore,
......[1]
Also, it is given in figure, 
Substitute in [1], we get;
Simplify:
Exterior- Angle sum Property states that if the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle.
then by Exterior angle sum property ;
Substitute the values given in the figure;
simplify;
therefore, the measure of angle ACB is, 
9514 1404 393
Answer:
(c) The less than symbol should be replaced with the less than or equal to symbol.
Step-by-step explanation:
"At most" means "less than or equal to". Madison needs to use ≤ instead of <.
Answer:
i think its 735
Step-by-step explanation:
since the base is a square it should be a whole square which is 7 and the height is 15 and v=whl and multiply all of it 7 times 7 is 49 times 15 is 735.
Answer:
Given:
- area = 18 cm²
- base = 6 cm
- height = (h + 1) cm
Substitute the given values into the equation and solve for h:
expand using distributive property of addition 
:
subtract 3 from both sides:
divide both sides by 3:
<u>To verify</u>:
Half of the base is 3 cm.
If h=5, then the height of the triangle is 6 cm.
Multiplying 3 by 6 is 18.
This matches the given area, so we can verify that h = 5.
