Answer:
Step-by-step explanation:
2.
Step where it was wrong ->
x-8 = 0
x=-8
They just put negative eight on the right side you have to cancel negative 8 out by adding negative 8 on both sides.
x-8=0
+8 +8
x=8 <- Right solution.
3.
Step where it was wrong ->
8(p-7) = 75
8p-7=75
Distributive Property you have to do 8 times p and 8 times -7, they just did 8 times p and forgot to do 8 times -7.
8(p-7)=75
8p-56=75 <- Do 8 * -7 in addition of doing 8 *p
8p=131
/8 /8
p = 16.735 or 131/8
13 and 15 blank be is 13 and blank a is 15
A. 2744 cubic units. Because you use the formula V=S^3
V=14^3 = 14x14x14= 2744
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:
.
