JMK’s angle is part of the right angle of JMN. The measurements there is 28°. A right angle is 90° so subtract 90 and 28 to get your angle measurement of JMK.
A small hint for the STR one is the fact that the straight lines are 180°. So Look at the line RTS. RTS is 180° by adding both the measurement of STR and STP. Simply subtract 180° with 118 to get STR.

Step-by-step explanation:
1) Convert mixed numbers to decimal numbers dividing the numerator by the denominator and adding the result to Whole number part:
![21+0.75=21.75\\\\2+0.5=2.5](https://tex.z-dn.net/?f=21%2B0.75%3D21.75%5C%5C%5C%5C2%2B0.5%3D2.5)
The unit rate is:
![Unit\ rate=\frac{21.75\ meters}{2.5\ hour}\\\\Unit\ rate=8.7\ \frac{meters}{hour}](https://tex.z-dn.net/?f=Unit%5C%20rate%3D%5Cfrac%7B21.75%5C%20meters%7D%7B2.5%5C%20hour%7D%5C%5C%5C%5CUnit%5C%20rate%3D8.7%5C%20%5Cfrac%7Bmeters%7D%7Bhour%7D)
2) Divide 2,857 points by 1,487 games:
![Unit\ rate=\frac{2,857 \ points}{1,487\ games}\\\\Unit\ rate=1.92\ \frac{points}{game}](https://tex.z-dn.net/?f=Unit%5C%20rate%3D%5Cfrac%7B2%2C857%20%5C%20points%7D%7B1%2C487%5C%20games%7D%5C%5C%5C%5CUnit%5C%20rate%3D1.92%5C%20%5Cfrac%7Bpoints%7D%7Bgame%7D)
3) Divide 255 strikeouts by 204 innings:
![Unit\ rate=\frac{255\ strikeouts}{204\ innings}\\\\Unit\ rate=1.25\ \frac{strikeouts}{inning}](https://tex.z-dn.net/?f=Unit%5C%20rate%3D%5Cfrac%7B255%5C%20strikeouts%7D%7B204%5C%20innings%7D%5C%5C%5C%5CUnit%5C%20rate%3D1.25%5C%20%5Cfrac%7Bstrikeouts%7D%7Binning%7D)
4) Divide 15 errors by 1,000,000 pieces:
![Unit\ rate=\frac{15\ errors}{1,000,000\ pieces}\\\\Unit\ rate=1.5*10^{-5}\ \frac{error}{piece}](https://tex.z-dn.net/?f=Unit%5C%20rate%3D%5Cfrac%7B15%5C%20errors%7D%7B1%2C000%2C000%5C%20pieces%7D%5C%5C%5C%5CUnit%5C%20rate%3D1.5%2A10%5E%7B-5%7D%5C%20%5Cfrac%7Berror%7D%7Bpiece%7D)
5) Divide 5,979 points by 179 career playoff games:

Hello
11 cm, 25 cm, 15 cm
if you add the lengths of two sides of the triangle, it must be greater than the length of the third side
therefore, the only possible lengths are 11 cm, 25 cm, 15 cm
Have a nice day

Answer:
x=12, y=6. (12, 6).
Step-by-step explanation:
3x-30=y
7y-6=3x
----------------
7y-6-30=y
7y-36=y
7y-y-36=0
6y-36=0
6y=0+36
6y=36
y=36/6
y=6
7(6)-6=3x
42-6=3x
36=3x
x=36/3
x=12
