For a.
Since there are already two angles given for the triangle, we can measure the last angle using this formula:
90 + 55 + a = 180
Now solve for "a".
90 + 55 + a = 180
145 + a = 180
a = 180 - 145
a = 35°
For b.
From the picture above, the two triangle's tip are touching and having to form <em>vertical angles. </em>This means that the angles are congruent to each other.
Now that we have two angles in the second triangle(35 and 120), we can use the same formula:
35 + 120 + b = 180
Now solve for "b":
35 + 120 + b = 180
155 + b = 180
b = 180 - 155
b = 25°
Answer:
the 4.25 m pipe because it is longer than 12.5 feet. The 3.75 m pipe is too short
Step-by-step explanation:
Answer: it will travel 16 miles on each of the remaining days.
Step-by-step explanation:
Total number of miles that the caravan will cross in the desert is 1378. It covered 22 miles on the first day and 28 miles on the second day. Total number of miles which the caravan covered on the first day and second day is 28 + 22 = 50 miles. Total number of miles left to be covered is 1378 - 50 = 1328.
Total number of days left is 85 - 2 = 83.
if the caravan travel the same number of miles on each of the remaining days, the number of miles travelled on each day would be
1328/83 = 16 miles
Answer:
x >-11
Explanation:
2x+7>-15
Subtract 7 from both sides
2x >-15-7
Simplify-15-7 to -22
2x >-22
Divide both sides by 2
22
x > - ___
2
Simplify 22/2 to 11
x >-11
