In the diagram shown, the area of the triangle is 44.3m². If b = 14.1m and the angle at C = 48°, work out x. Round to 1 DP. X C
1 answer:
If the height of the triangle will be 6.28 meters. Then the value of x will be 8.46 meters.
<h3>What is the triangle?</h3>A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In the diagram shown, the area of the triangle is 44.3 m².
If b = 14.1 m and the angle at C = 48°.
Then the value of x will be
The height of the triangle will be
A = 1/2 × B × H
44.3 = 1/2 × 14.1 × h
h = 6.28 m
Then the value of x will be
sin 48° = 6.28 / x
x = 8.455 ≈ 8.46 m

Olivia sold 14 magazines.
Step-by-step explanation:
Total magazines sold = 138
Let,
Magazines sold by Olivia = x
Magazines sold by Quincy = y
Magazines sold by Trenton = z
According to given statements;
x+y+z=138 Eqn 1
Quincy sold three times as many magazines as Olivia.
y = 3x Eqn 2
Trenton sold two less than twice the number of magazines that Quincy sold.
z = 2y-2 Eqn 3
Putting value of y from Eqn 2;
Putting value of y from Eqn 2 and value of z from Eqn 3 in Eqn 1
Dividing both sides by 10
Olivia sold 14 magazines.
