Answer:
Step-by-step explanation:
The sum of the measures of the angles in a triangle is 180°.
X + Y + Z = 180°
84° +(r +59)° +(r +51)° = 180°
2r +194 = 180 . . . . . . . . . divide by ° and simplify
2r = -14 . . . . . . . . . . subtract 194
r = -7
Then the measure of Y is ...
Y = (r +59)° = (-7 +59)°
Y = 52°

<em>Additional comment</em>
Z = 44°
Answer: 1/24
Step-by-step explanation:
you need to use kcf ( keep the first fraction change division into multiplication and flip the other fraction)

Answer:
Given that in the jar, navy beans and white beans in a ratio of 1:9. Let the amount of navy beans be x.
Then, the amount of white beans in the jar is 9x.
Given that amount of navy beans is x=90
Total amount of beans in the jar is x+9x=10x=10+90=900
So the ratio is 1:9
