What is the measure of angle c in degrees? * 150 30 90 60

Dmitry [639]

Answer:

Option (2)

Step-by-step explanation:

Measure of angle formed by two tangents from a point outside the circleis half the difference of the measures of the intercepted arcs.

From the figure attached,

m∠C = $\frac{1}{2}[m(\text{major arc AB})-m(\text{minor arc AB)}]$

= $\frac{1}{2}[(360-m\widehat{AB})-m(\widehat{AB})]$

= $\frac{1}{2}[360-2m(\widehat{AB})]$

= $180-m\widehat{AB}$

= 180 - 150

= 30°

Therefore, measure of angle C will be 30°.

Option (2) is the answer.

How do you evaluate 3ab

dimaraw [331]

Lets say a=2 and b=5 you now plug in you numbers to get 3x2x5 we know 3x2=6 so now take 6 and multiply it by 5 so 6x5=30 you can also set this equal to 0 3ab=0 then divide by either a or b ill show you both if you divide by a you are left with 3b=a if you divide by b than you get 3a=b
