Answer:
A = 140 in²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
here b = 20 and h = 14 , then
A = × 20 × 14 = 10 × 14 = 140 in²
Answer:
D a reflection over the x axis by a reflection over the y axis
Step-by-step explanation: if u put the triangle on the button left up then move it to the upper right it’s congruent.
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Let x represent the smaller angle:
x + (x + 81.2) = 180
2x + 81.2 = 180
2x = 98.8
x = 49.4 degrees
therefore:
smaller angle = 49.4 degrees
larger angle = 49.4 + 81.2
= 130.86 degrees
0.03*0.05 is equal to 0.15 but less than 0.2 and greater than 0.1
