ECD=90 ECD=x+5+3x-7=4x-2, 4x-2=90, 4x=92, 4x/4=92/4, x=23
a) 23
ECH=x+5, 23+5=28, ECH=28
b)28
HCD=3x-7, 3(23)-7, 69-7=62 HCD=62
c)62
GCF & ECH are vertical angles, GCF=28
d) 28
ECF=180, 180-28(GCF)=152, ECF=152
e) 152
DCF=90, 90+28(GCF)=118
f) 118
Paul forgot to divide by 2. The area of a triangle is A = 1/2 * b * h
Paul just multiplied the Base and height together. 5*16 = 80.
Paula used the formula correctly. The answer is 40 square meters.
Answer:
The dimensions are length=32 inches and width=24 inches
Step-by-step explanation:
Recall that perimeter of a rectangle is
The ratio of its length to width is 4:3.
This implies that,
We substitute P=112 inches, and l in terms of w to get;
The length is
Answer:
The two triangles are related by congruent angles/similarity, so the triangles are similar.
Have an awesome day! :D
