Help me with this please! i have to find the surface area
2 answers:
What is required in this is to find the area of each piece.
First rectangle (top)
A=13*4
A=52
Second rectangle (bottom)
A=12*4
A=48
Third rectangle (left side)
A=5*4
A=20
Triangles (both (causing us to multiple by 2 in the problem) because they have the same length and width)
A=1/2*5*12*2
A=5*12 (1/2 and 2 cancel out)
A=60
Now add them up:
52+48+20+60=SA (remember 60 is both triangles so we only have 4 measurements)
180=SA
Answer:
There are 5 surface areas.
Left rectangle = 5 x 4 = 20 square inches
Tilted top rectangle = 13 x 4 = 52 square inches
Bottom Rectangle = 12 x 4 = 48 square inches
Side triangles = 5 x 12 x .5 = 30 square inches EACH
Total area = 20 + 52 + 48 + 30 + 30 =
180 square inches

Answer:
58 degrees
Step-by-step explanation:
well we know that every angle in a tringle adds up to 180 degrees.
so we know that 64 + angle 1 + angle 2 = 180
180-64=116
and since they are congruent (same value as one another) you just divide 116 by 2 and boom!
116/2=58
both are 58 degrees
Answer:
-1 and 10
Step-by-step explanation:
Here we answer the question: "What two numbers multiply to -10 and add up to 9?"
The answer to your question is:
-1 and 10
Y = mx + b
m = (y2 - y1)/(x2 - x1)
y = (26,600 - 18100)/(20 - 10)x + b
y = 850x + b
18100 = 850(10) + b
b = 9600
R(x) = 850x + 9600
Answer:
2x+3y+4z
Step-by-step explanation:
The answer would be x=15+\sqrt{258},\:x=15-\sqrt{258}
