Recall that the interior angles of a quadrilateral add up to 360 degrees.
1) Let x be the measure of the missing angle, then we can set the following equation:
Solving for x we get:
2) Let y be the measure of the missing angle, then we can set the following equation:
Solving for y we get:
Answer:
1) 100 degrees.

Answer:
%7 of 10 is -> 0.7
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Stephen king wants to know what 7% of 10 is
%7 * 10 = x
0.07 * 10 = x
<u>Step 2: Multiply</u>
0.07 * 10 = x
<em>0.7 = x</em>
<em />
Answer: %7 of 10 is -> 0.7
Answer:
Step-by-step explanation:
40 : 30 = x : 63 ⇒ x = (40*63)/30 = 84
y = 59°
Answer:
223 and 224
Step-by-step explanation:
Divide 447 by 2. It gives a decimal of 223.5, but obviously you don't have half pages. So the page number would be 223 and 224.
Answer:
12.5 miles per hour.
Step-by-step explanation:
There are 60 minutes in 1 hour so:
12 minutes = 12/60 = 1/5 of an hour.
So his speed in mph
= distance in miles / time in hours
= 2.5 / 1/5
= 2.5 * 5
= 12.5 miles per hour.
