Answer:
A
Step-by-step explanation:
The angle adjacent to 133 and 133 form a straight angle and are supplementary, hence
adjacent angle = 180° - 133° = 47°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles. The angle 90 is an exterior angle, thus
p + 47 = 90 ( subtract 47 from both sides )
p = 43° → A
Answer:
<h3>2.2</h3>
Step-by-step explanation:
- (6y-22) = (y-11)
- 6y-22 = y-11
- 6y-y = -11+22
- 5y = 11
- y = 11/5
- y = 2⅕ or 2.2

Answer:
There were approximately 53 cases of measles before the increase.
Step-by-step explanation:
Since there was an increase of 10.2% this means that the value we have now is the value we had prior plus the increase, in other words this is 100% of the cases before the increase plus 10.2%, so we have now 110.2% of cases. We know that this value represents 58 cases, so we can use a rule of three in order to determine the prior value. This is seen bellow:
100% -> x
110.2% -> 58
110.2*x = 100*58
x = 5800/110.2 = 52.63
Which is approximately 53 cases.
