The answer would be
B. Subtract 12 - 4
(Hope this helps)
(7) m∠A = 52°
(8) m∠B = 117°
Solution:
(7) Let us first define the supplementary and complementary angles.
Supplementary angles: Two angles are said to be supplementary angles if their sum is add up to 180°
Complementary angles: Two angles are said to be complementary angles if their sum is add up to 90°
Given supplement of 142° = 180° – 142°
= 38°
Complement of ∠A = Supplement of 142°
⇒ Complement of ∠A = 38°
Measure of ∠A = 90° – 38°
= 52°
Hence m∠A = 52°.
(8) Given complement of 27° = 90° – 27°
= 63°
Supplement of ∠B = Complement of 27°
⇒ Supplement of ∠B = 63°
Measure of ∠B = 180° – 63°
= 117°
Hence m∠B = 117°.
If we assume the pool to be a semi sphere, then the volume would be
<span>
V pool = 1/2 * [4/3*pi*r**(3)]
</span>where r is the radius = 50m
V pool = 1/2 * [4/3*3.14*50**(3)]
<span>
V pool = 261799.3878 m</span>³
If we round up >>> V water in the pool = 261800 m³<span>
</span>
Answer:
The steps are more or less the same, except for one new addition:
1. Divide the tens column dividend by the divisor.
2. Multiply the divisor by the quotient in the tens place column.
3. Subtract the product from the divisor.
4. Bring down the dividend in the one's column and repeat it.
Step-by-step explanation:
Answer should be 5,6,8 if that is an answer choice
