What is the value of x?

Mathematics
1 answer:
uranmaximum [27]2 years ago
6 0

Answer:

x=\frac{160-51}{2} =54.5°

Step-by-step explanation:

"Theorem 9-13: The measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside the circle is equal to half the difference of the measures of the intercepted arcs."

Basically no matter what other circle, secant or tangent you get, you just use the formula Outer\angle=\frac{far.point - near.point}{2}

If you need the outer angle, just put the other angles in and solve

If you need the far or near point angle, re-arrange the formula to get that value.

Identify the base in this statement:<br> 16% of 98 is 15.68
Darya [45]

Ans: The base in the statement “16% of 98 is 15.68” is 98.

The three quantities in problems involving percent are Percent, Base, amount. ‘Percent’ has the percent (%) symbol. The base is the whole amount and the amount is the amount which comes after calculation the percent of the total amount.

So, in above problem, total amount i.e. Base is 98

Percent is 16%

And, the amount is 15.68.

<span>Moreover, the base in the statement comes after the word ‘of’ and in above statement, the digit after ‘of’ is 98.</span>

Find the value of x
Lostsunrise [7]

Step-by-step explanation:

In a right angle triangle one angle is 90°

w.k.t sum of angles in a triangle is 180°

thus, 2x+15+x+90°=180°

3x+105°=180°

3x=75°

x= 75/3=25°

Hope this helps you.
