Answer:
The dimensions on the scale drawing would be 1 inch by 0.8 inches.
The scale is 1 in: 10 ft; since the actual width of the deck is 10 ft, then it will be 1 inch on the scale. To find the width:
1/10 = x/8
Cross multiply:
1*8 = 10*x
8 = 10x
Divide both sides by 10:
8/10 = 10x/10
0.8 = x
The width on the scale drawing will be 0.8 inches.
Answer:
x ≈ 3.9
Step-by-step explanation:
Call the segment shared by the two triangle "y". The Pythagorean theorem tells you ...
sum of squares of sides = square of hypotenuse
y² +6² = 10²
x² +7² = y²
Substituting for y² using the second equation, we get ...
x² +7² +6² = 10²
x² = 10² -7² -6² = 100 -49 -36 = 15
Taking the square root, we find ...
x = √15 ≈ 3.9

Step by step explanation:
Answer: 6
Step-by-step explanation: To find the side length of a square, you need to find the square root of the area because the side length squared is the area.
Answer:
Step-by-step explanation:
use known angles and rules to find unknown values
vertical angles (pairs of angles on opposite sides of an intersection) are equivalent
supplementary angles (angles found next to each other on a line) add up to 180 degrees
opposite interior angles are equivalent
And I don't remember the name of this kind of angle, but angle 1 and 10 are equivalent because they are found on the same "location"
using these rules you can find all missing angles.
1= 75
2=180-75=105
