Answer:
The measure of ∠A is 127° .
Step-by-step explanation:
The interior angles of a triangle always add up to 180°. Since you can fix <em>three</em> triangles into a pentagon, the sum of its interior of angles is 540° You could also look at how many angles there are (5), multiply that number by 180°, then subtract 360° from the product.
540° - (113° + 80° + 130° + 90°) = ∠A
540° - 413° = 127°
∠A = 127°

Answer:
127
Step-by-step explanation:
The sum of interior angles in this rectangle is = 540
three angles are given and one of the angle is a right angle so it's 90 degrees
80 + 130 + 90 + <A + 113 = 540 add like terms
413 + <A = 540 subtract 413 from both sides
<A = 127

Answer:
x = 6 2/3
Step-by-step explanation:
3x-4=16
3x=16+4
3x=20
x=20/3
x= 6 2/3 or 6.66666666666
Answer:
x=5
Step-by-step explanation:
20(20-x) = 300
Divide each side by 20
20/20(20-x) = 300/20
20-x = 15
Subtract 20 from each side
20-x-20 = 15-20
-x = -5
Multiply each side by -1
x = 5
10 more than 23 is 33 because 10 +23 = 33.
Answer:
table one
Step-by-step explanation:
because the table is split in to four different tables but it is put together and so the one that is the highest is the first table
