AC is tangent to circle o at point C.What is the measure of <OAC​

Mathematics

<em>∠OAC = 27°</em>

Step-by-step explanation:

When a line is tangent to a circle, the part where the radius meets with the line of tangency will be a right angle. Since we know this, we know that ∠C is equal to 90°. We also know that all of the angles in a triangle will add up to be 180°.

We can now add up the two angles we know and subtract it from 180° to get the measurement of ∠OAC.

90+63=153

180-153=27

∠OAC = 27°

Please help this is geometry and I am not quite sure how to solve this one
Lyrx [107]

Answer:

x = 1

y = 1.7

z = 60⁰

work:

z = 60 because the three angles add to 180⁰ and 180⁰ - 90⁰ - 30⁰ = 60⁰

in a 30-60-90 triangle, the hypotenuse is twice the length of the shorter leg, so x = 1.

the longer leg is the short leg * Sq rt of 3

Sq rt of 3 to the nearest tenth is 1.7, so 1.7 * 1 is still 1.7, so y = 1.7.
