Answer:
for perimeter you add all sides. so Lenth x2 + width x2 is 24+30 which would equal 54
for area it's Lenth times width so 12 times 15 equals 156
Answer:
x > 3
(x is greater than 3)
Step-by-step explanation:
Let the number be x
According to given condition:
Five less than twice a number > number - 2
Mathematically,
2x - 5 > x - 2
Adding 5 on both sides to simplify the expression:
2x > x - 2 + 5
2x > x + 3
Subtracting x from both sides we get:
2x - x > 3
x > 3
So this the simplified expression.

Answer:
c. sin 30 is positive and sin -30 is negative
Step-by-step explanation:
Picture the unit circle (which is attached). <u>Sine is like the y-coordinate.</u> And -30 and 30 on the unit circle both form equally-sized triangles, but -30 is underneath the x-axis, so it has a <u>negative y-coordinate.</u> 30 is above the x-axis, so it has a <u>positive y-coordinate.</u>
Right triangle

Given hypothenuse = 10
Adjacent = x
And angle degree of 52
You can use Cosine
Cos(52) = x/10
0.6156614753 = x/10
x = 6.156614753
Round to nearest tenth
Solution: 6.2
