a) CE = 16 ft
b) BC = 6√2 ft [ BY Pythagoras theorem]
c) m angle CFD = 90°
d) m angle DBE = 90°
It's closer to 4.97 because if you round to the nearest tenths, you will get 4.97.
Given:
In triangle XYZ, x = 27 cm, y = 79 cm and .
To find:
The length of z.
Solution:
In triangle XYZ, using the Law of cosine, we get
Putting the given values in the above formula, we get
Taking square root on both sides.
Approx the above value to the nearest number and side length cannot be negative. So,
Therefore, the length of z is about 102 cm.
Answer:
- 6p - 21
Step-by-step explanation:
<u>Property used:</u> a(b+c) = ab + ac
- -6( -3p + 6 ) + 3( -8p + 5 ) =
- (-6)(-3p) + (-6)(6) + 3(-8p) + 3(5) =
- 18p - 36 - 24p + 15 =
- (18 - 24)p - (36 - 15) =
- - 6p - 21
