Answer: C
Step-by-step explanation:
(-2) (4) is negative
(-6)(-3) is postive
negative * positive = negative
Negative, because the product (−2)(4) is negative and the product (−6)(−3) is positive, and the product of a negative number and a positive number is a negative number

Answer:
11.28m
Step-by-step explanation:
The computation of the height of the spire is shown below:
let us assume the height of the spire be x
Now
For triangle ABD
Tan 43 degrees = h ÷ x
x = h × cot 43 degrees
= 1.07236 h
For triangle ABC
tan 15 degrees = h ÷ (30 + x)
0.2679 = h ÷ 30 + 1.07236h
8.038 + 0.28728 h = h
h = 11.28m
Answer:
x = -2 or -12
Step-by-step explanation:
That is the solution above
