Answer:
B. 8.56
Explanation:
<u>Given</u>:
<u>So using </u><u>cosine </u><u>rule</u>:
Answer: 28+14 = 7 (4+2)
Step-by-step explanation:
- The first option is incorrect because after you distribute 7 into (4 + 14), you get 28 + 14 = 28 + 98.
- The second option is incorrect because after you distribute 4 into (7 + 2), you get 28 + 14 = 28 + 8.
- The third option is incorrect because after you distribute 4 into (14 + 28), you get 28 + 14 = 56 + 112.
- The fourth option is correct because after you distribute 7 into ( 4 + 2), you get 28 + 14 = 28 + 14.
To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right.
D. 25% as there are 8 sections and two wanted outcomes this can be simplified into a 1/4 so 1/4=25%
A linear pair is a pair of adjacent, supplementary angles which sum is equal 180
So
5x + 5 + 11x - 65 = 180
16x - 60 = 180
16x = 240
x = 15
<PQR = 5(15) + 15 = 75 + 5 = 80
Answer
80°
