Find the measures of the missing angles (picture attached)
ella [17]
Here, sum of all the angles would be equal to 360.
We can see there are two right angles (=90)

So, 90 + 90 + x + 60 = 360
240 + x = 360
x = 360 - 240
x = 120

In short, Your Answer would be 120

Hope this helps!

m and n on number line

Required

Which is true

From the attachment, we have:

n >m

n > 0 and m < 0

(a):\ n - m

Since: the above inequalities are true, then:

n - m > 0

(a) is true

<em>There is no need to test other options; since (a) is true</em>

Lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?
MatroZZZ [7]

Answer:

28

Step-by-step explanation:

Neat Question.

Thanks for posting.

The straign line (horizontal) makes an isosceles triangle inside the circle. So the bottom angle of the triangle is also 59 degrees. The central angle of the interior triangle is

180 - 59 - 59 = 62.

x and the 62 degree angle are complementary -- both are in the 90 degree angle triangle made by the tangent. x + 62 = 90

x = 90 - 62 = 28
