Answer:
The measure of the largest angle is 72º.
Step-by-step explanation:
We will first solve for x. We know that the sum of the interior angles of a triangle is 180º, so 15x + 21x + 24x is equal to 180º. This means that 60x = 180º, so x = 3º. The largest angle is 24x, which is 72º.
Answer:
X = 13 (rounded off to one decimal place)
STAY SAFE GOD BLESS YOU
Step-by-step explanation:
X² = H² - b²
X² = 23² - 19²
X² = 529 - 361
√x² = √168
X = 12.9614
X = 13 (rounded off to one decimal place)
Answer:
total marbles in the box is 600
18 - 22 + 5x(66:3)
= 18 - 22 + 5x22
= -4 + 110
= 77
