the circle below has center T. suppose that m UV = 138 degrees and that UW is tangent to the circle at U. find the following
alisha [4.7K]

Angle UTV is basically given: it's 138°.

Moreover, since UTV is isosceles, the other two angles have the same measure x. We thus have

138+x+x=180 \iff 2x=42 \iff x=21

So, TUV is 21°, and VUW is complementary, so it must be 69° so that they sum up to 90°

the difference between two numbers is 9. three times the smaller is equal to twice the larger. what are the numbers?
Sergio039 [100]

Answer: 27 and 18

Step-by-step explanation:

x - y = 9  → x = 9 + y

3y = 2x

3y = 2(9 + y)

3y = 18 + 2y

3y - 2y = 18

y = 18

2x = 3(18)

2x = 54

x = 27

x - y = 9

27 - 18 = 9

9 = 9

7m = 49 solve the equation by trial and error method​
Ymorist [56]

Trial and error specifies that you should guess the value of m and see if you aimed too low too high then adjust your next guess based on that.

Suppose we don't already know what m is (even though it is completely obvious), let's pick m to be 6,

So we check, 7\cdot6=42 but 35\lt49 which means m must be bigger.

So we pick m to be 8 and check, 7\cdot8=56 but 56\gt49 which means m must be smaller.

Since only natural number between 6 and 8 is 7 we pick m to be 7 and check, 7\cdot7=49 and 49=49.

The answer is therefore 7.

Hope this helps :)
