(5 + 4 - 2) x (-2)
= (9 - 2) x (-2)
= (7) x (-2)
= - 14 (Answer A)
For this case, the first thing to do is find the scale factor.
Using the measure of height we have:
k = (360) / (18 * (1/12))
k = 240
Thus, the length of the building is:
(14 * (1/12)) * (240) = 280 feet
Answer:
The lenght of the real building is:
280 feet
Answer:
C
Step-by-step explanation:
You first distribute within the parentheses which is -(-z-2). This is going to make everything positive as everything in the parentheses is negative. You should get z+2. Next, you plug that back in. It should be-3z+z+2. You simplify to get -2z+2. Hope this helps!
Answer:
B
Step-by-step explanation:
You are given two sides and the included angle, so you need to use the law of cosines.
c² = a² + b² - 2ab cos C
c² = 12² + 13² - 2(12)(13)cos 134°
c² = 313 - 312(-0.6947)
c² = 529.733
c = 23.016
Now use the law of sines.
c/sin C = a/sin A
23.016/sin 134° = 12/sin A
sin A = 12 × sin 134° / 23.016
sin A = 0.37504
A = 22.03°
B = 180° - 134° - 22.03°
B = 23.97°
m<A = 22°; m<B = 24°; c = 23 km
Answer: B
