Answer:
<h2>b. 40 yd²</h2>
Step-by-step explanation:
We have the square and the right triangle.
The formula of an area of a square:
a - length of side
The formula of an area of a right triangle:
a,b - legs
We have:
SQUARE:
a = 4 yd
RIGHT TRIANGLE:
a = 6 yd, b = 4 yd + 4 yd = 8 yd
The area of the figure:
Answer:
Step-by-step explanation:
b = 20 °
c = 160° ( b/c 180-20 = 160 ) :)
Answer:
Step-by-step explanation:
Simplifying
25m + 22 = 9m
Reorder the terms:
22 + 25m = 9m
Solving
22 + 25m = 9m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-9m' to each side of the equation.
22 + 25m + -9m = 9m + -9m
Combine like terms: 25m + -9m = 16m
22 + 16m = 9m + -9m
Combine like terms: 9m + -9m = 0
22 + 16m = 0
Add '-22' to each side of the equation.
22 + -22 + 16m = 0 + -22
Combine like terms: 22 + -22 = 0
0 + 16m = 0 + -22
16m = 0 + -22
Combine like terms: 0 + -22 = -22
16m = -22
Divide each side by '16'.
m = -1.375
Simplifying
m = -1.375
Answer:
DAB = BCD
Step-by-step explanation:
DAC = BAC = 90 degrees and DAB = ABC = 90 degrees don't work because they're both equilateral triangles and don't have a right angle that would equal 90. DAB = ABC are clearly not congruent so the answer is DAB = BCD. Also DAB = BCD share the same midsection line.
I think it is 104 hope it is right
