Answer:

30 degrees

Step-by-step explanation:

This is an isosceles triangle having 2 equal sides and 2 equal base angles.

since the measurement of all the internal angles of the triangle is 180 degrees and we know that each base angle is 75 degrees

solving for x:

75 + 75 + x = 180 degrees

150 + x = 180

x = 180 - 150

x = 30 degrees

Julia has to mow two yards she will need 13/16 gallon of gas to mow the first yard and 2/5 gallon to mow the second yard she has

Mazyrski [523]

Answer:

Julia has enough gas to mow the two yards.

Step-by-step explanation:

Given:

Julia needs $\frac{13}{16}$ gallon of gas to mow first yard.

Julia needs $\frac{2}{5}$ gallon of gas to mow second yard.

Julia has a total of $1\frac{1}{2}$ gallon of gas in in her can.

To find whether she has enough to mow both yards.

Solution:

Total gallons of gas needed to mow two yards can be found out by :

⇒ $\frac{13}{16}+\frac{2}{5}$

Taking LCD =80.

⇒ $\frac{13\times 5}{16\times 5}+\frac{2\times 16}{5\times 16}$

⇒ $\frac{65}{80}+\frac{32}{80}$

Adding the numerators.

⇒ $\frac{97}{80}$

⇒ 1.2125 gallons

Julia has $1\frac{1}{2}$ gallon = 1.5 gallons of gas in in her can.

Since $1.5>1.21$ , thus we can say that Julia has enough gas to mow the two yards.
