Answer:
14cm^2
Step-by-step explanation:
Area of a triangle is (base×height)/2
(4×7)/2
28/2
=14 centimetres squared
Angle B is 36. Hope this helps. :)
Answer:
where is part b? Part A is 4/13
Step-by-step explanation:
this is because in total there are 13 marbles. and when you pull out a marble. 4 of them can be red. you can simplify that fraction if need be.
Answer:
x=10
m=3
Step-by-step explanation:
The angles are the same since the sides are the same length (isosceles triangle)
55 = 5x+5
Subtract 5
55-5 =5x+5-5
50 = 5x
Divide by 5
50/5 = 5x/5
10=x
The altitude is a perpendicular bisector so
5m-3 = 2m+6
Subtract 2m from each side
5m-3-2m = 2m+6-2m
3m-3 = 6
Add 3 to each side
3m-3 +3 =6+3
3m =9
Divide by 3
3m/3 = 9/3
m =3
Answer:3
