ANSWER:
Let hypotenuse be h.
On using trigonometric function, we get.
sin52° = 12/h
0.788 = 12/h
h = 12/0.788
h = 15.2 rounded.
The expression -1 × 2 × -3 × 4 × -5 has a negative value ⇒ C
Step-by-step explanation:
Let us revise the products of negative and positive
- (+) × (+) = (+)
- (-) × (-) = (+)
- (-) × (+) = (-)
- (+) × (-) = (-)
- The product of three (-) is (-) ⇒ -2 × -3 × -1 = -6 (-2 × -3 = 6 × -1 = -6)
- The product of four (-) is (+) ⇒ -2 × -3 × -1 × -4 = 24 (-2 × -3 = 6 × -1 = -6 × -4 = 24)
- If there are even negative signs, then the product will be positive
- If there are odd negative signs, then the product will be negative
A. -1 × -2
∵ There are two negative signs
∵ 2 is an even number
∴ -1 × -2 has a positive value
B. 1 × -2 × -3 × -4 × -5
∵ There are four negative signs (-2 , -3 , -4 , -5)
∵ 4 is an even number
∴ 1 × -2 × -3 × -4 × -5 has a positive value
C. -1 × 2 × -3 × 4 × -5
∵ There are three negative signs (-1 , -3 , -5)
∵ 3 is an odd number
∴ -1 × 2 × -3 × 4 × -5 has a negative value
D. 1 × -2 × 3 × -4 × 5
∵ There are two negative signs (-2 , -4)
∵ 2 is an even number
∴ 1 × -2 × 3 × -4 × 5 has a positive value
The expression -1 × 2 × -3 × 4 × -5 has a negative value

Answer:
m<5 is 105
Step-by-step explanation:
<5 and <4 are alternate interior angles meaning they are congruent to each other.
i don't know if there is a graph for this problem, but m1 should always equal m2
if m1 and m2 are parallel, one line that is perpendicular to m1 is always perpendicular to m2, and the slopes of m1 and m2 are equal and their lines should never intersect
