Find the measure of angle A

Mathematics
1 answer:
amid [387]3 years ago
8 0

Step-by-step explanation:

The sum of angles in a triangle = 180°

Therefore,

(7x - 6)° + (5x - 10)° + 52° = 180°

Collect the like terms and add

7x + 5x - 6 - 10 + 52 = 180°

12x + 36 = 180°

12x = 180 - 36

12x = 144

x = 144 / 12

x = 12°

From the above diagram,

Angle A = 7x - 6

A° = 7(12) - 6

A° = 84 - 6

A = 78°

zlopas [31]

Answer:

A.b ≤ 40

Step-by-step explanation:

Janice weighs 130 pounds so you must take away his weight from the weight limit (250 pounds). That will give you 120. 120 pounds can still be put on the truck. Since each block weighs 3 pounds, you have to divide 120 divided by 3, giving you 40. Janice can carry up to 40 blocks on the truck each trip.
