What is the value of angle x°?

erastova [34]

Answer:

$64^\circ$

Step-by-step explanation:

Please refer to the attached figure for the labeling and construction in the given figure:

Given that minor angle of arc AB is $116^\circ$ .

Or in other words, we can say that angle subtended on the center O by the arc is $116^\circ$ .

Now, PA and PB are the tangents so, if we join the center of circle O with A and B, the angles formed are right angles.

i.e.

$\angle PAO = 90^\circ\\\angle PBO = 90^\circ$

Now, we know that sum of internal angles of a quadrilateral is equal to $360^\circ$ .

Here, we have the quadrilateral AOPB.

$\therefore \angle PAO +\angle PBO+\angle AOB +\angle APB=360^\circ\\\Rightarrow 90+90+116+x=360^\circ\\\Rightarrow x = 360 - 180 - 116\\\Rightarrow x = 64^\circ$

Hence, the correct answer is:

$x = 64^\circ$

Anyone know how to do this ? If so can u help me ? Thanks <3

Answer:

24.1 x 10^4 = 241000 .056 x 10^7 = 560000 507 x 10^-5 = 0.00507

Step-by-step explanation:

for scientific notation, all you need to do is start at the decimal point (or end of whole number) and move over the amount of spaces (the exponent) to the right. if it is a negative exponent, instead of moving to the right, you should move to the left.

for example : 500 x 10^3

when you start from the last zero and move to the right, you need to fill the space with three zeroes.

so 500 x 10^3 = 500,000.
