What is the value of angle x°?

Mathematics

erastova [34]3 years ago

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

5. Expla in why 4 is or is not a multiplicative inverse mod 10 of 7.
AnnZ [28]

Answer:

  4 is not. (3 is)

Step-by-step explanation:

A number is the multiplicative inverse of 7 (mod 10) if the product mod 10 is 1.

7 × 4 mod 10 = 28 mod 10 = 8 . . . . not 1

The tax on a property with an assessed value of $90,000 is $1,200. What is the assessed value of a property if the tax is $2,200
Ivanshal [37]
I'm not 100% sure but this is how I would try.
If you don't get a better answer, check this w/your teacher.

x/100 *90,000 = 1200

90,000x = 120,000

x = 1.3% tax percentage

1.3/100x = 2200

1.3x = 220,000

x = $169,230.77 assessed value

Triangle X Y Z is shown. The length of X Z is 12, the length of Y Z is 11, and the length of Y X is 6.
LenaWriter [7]

Answer:

84 degrees

Step-by-step explanation:

Applying the Cosine Rule (Choice 2 is the correct one)  :-

12^2 = 11^2 + 6^2 - 2*11*6 cos Y

144 = 121 + 36 - 132 cos Y

cos Y = (121 + 36 - 144) / 132

cos Y = 0.09848

Y = 84.3 degrees
