Answer:80 feet
Step-by-step explanation:
Sum of < in a triangle is 180°
<G + <E + <F=180°
90 + 20 + < F = 110
< F = 70°
Using sine rule
sin G\EF = sin F\EG
sin90°\EF = sin70°\75
EF = 75sin90°\sin70°
= 79.81
=80 to the nearest tenth feet.
Answer:
x =60 ° angles on a straight line
y+25° =120° exterior angle of the triangle
y=120°-25°=95°
y =95 °
Answer:
The subtraction property of equality
Option A is correct
Explanation:
The given equation is:
12 - x = 7x + 32
Subtract 12 from both sides
12 - 12 - x = 7x + 32 - 12
-x = 7x + 20 (Step 1)
From step 1 above, subtract 7x from both sides
-x - 7x = 7x - 7x + 20
-8x = 20 (Step 2)
Since we subtracted 7x from both sides to get step 2, the justification for step 2 is the subtraction property of equality
Answer:
36 1/4 inches
Step-by-step explanation:
Subtract 38 1/2 from 74 3/4:
74.75 - 38.5
= 36.25 or 36 1/4
So, the vertical measurement of the bulletin board is 36 1/4 inches
1. lines j and k because they have the same slope.
2.d because -1/3 is the opposite slope of 3 and it passes through that point.
