Answer:
Isosceles triangle:
* two sides are equal.
* the base angle are always equal and
* the altitude is a perpendicular distance from the vertex to the base.
Since, the triangle ABC is an isosceles and AC is the base
⇒ AB=BC and 
Also, AD is the angle bisector of 
, which implies that it cuts the angle at A in two equal halves,
let 
, then the bisectors cuts it in 
.
As per the given information, we know 
is 110°, therefore, the line BDC forms a supplementary angle;
⇒
As shown in picture given below:
By sum of all interior angles in a triangle is 180 degree, thus
or
Simplify:
Therefore, the 
.
Now, to find the angle B, we have;
[Sum of the measure of the angles in a triangle is 180 degree]
or
or
Simplify:
.
This question relates to scale factor
As you can see triangle DEF has been enlarged from triangle ABC
Two sides are given, so you can find the scale factor.
20/6=10/3=3.3333333
Multiply 24 by 10/3 to get x
Which gives you 80
c=80cm
170? I think. I don't really understand your question
Answer:
90%
Step-by-step explanation:
Is means equals and of means multiply
135 = P * 150
Divide each side by 150
135/150 = 150P/150
.9 =P
Change this to percent form by multiplying by 100%
.9*100%
90%
