Answer:
A. 28
Step-by-step explanation:
Recall that the sum of all of the angle of a triangle must be 180 degrees. As we have 2 of the angles, we can subtract these angles from 180 to find the missing angle
![180-95-57=28](https://tex.z-dn.net/?f=180-95-57%3D28)
The answer is A
It is A because in an isosceles triangle, only 2 sides are congruent and it is possible to have all acute angles eg. 55, 55 and 70
Answer:
12
Step-by-step explanation:
Direct Variation. I think it's gonna be like this.
SInce Z is not inversely to y , its varies directly to both.
Then it's,
Z=kxy, where k is constant.
subst. Z=6,x=2 and y=6.
6=k×2×6
6=k×12=12k
6=12k=½
the formula connecting them is
Z=½xy
Z=½×3×8
Z= 1×3×8÷2
Z=24÷2
Z=12.
That's my solution.
Answer:
Step-by-step explanation:
If there are 90 students and the ratio of boys to girls is 3:2, that means 3x+2x=90
Combine like terms: 5x=90
x=18
2x (girls)=36
3x (boys)=54
1/3 of the boys scored full marks, so 54/3=18 boys scored full marks
The number of girls who scored full marks is half of the number who did not score full marks means that 1/3 of the girls scored full marks. 36/3=12, so 12 girls scored full marks.
(I don't know what the question is sorry if it's incorrect but there's not enough information)
Hope this helps!
