Angle of a triangle measures 115° the other two angles are in the ratio of 4:9 what are the measures of those two angles
1 answer:
Answer:
20, 45
Step-by-step explanation:
A triangle has 180 degrees interior angle measure. One angle measure 115 so that means the other two angles must add up to 65.
The remaning angles form a ratio of 4:9. This means we must split 65 into a ratio of. 4:9
A ratio partition parts of something. We can add the ratio intergers to find it full length.
4+9=13.
Divide 65/13=5.
Multiply 5x4 and 5x9 serpately.
We get 20 and 45

Answer:
they will each receive $1.75
Step-by-step explanation:
5.50*5= 27.50
12.75*5= 63.75
27.50+63.75= 91.25
20*5= 100
100-91.25=8.75
8.75/5= $1.75

Answer:
Step-by-step explanation:
roots are (2+3i) and (2-3i)
reqd. eq. is (x-2-3i)(x-2+3i)=0
or (x-2)²-(3i)²=0
or x²-4x+9-9i²=0
or x²-4x+9+9=0
or x²-4x+18=0
