Step-by-step explanation:
this is not an isoceles triangle.
anyway, we need to remember 2 things :
1. the sum of all angles in a triangle is always 180°.
2. the sum of all angles around a single point on a line is 360° (as this point wound be the center of an invisible circle). and as the line cuts this circle in half, the angles on one side of the line around this point is therefore 180°.
so, the internal angle Q is then
180 = 50 + 55 + Q
Q = 180 - 50 - 55 = 180 - 105 = 75°
the exterior angle x at Q is then
180 = Q + x = 75 + x
x = 180 - 75 = 105°

Step-by-step explanation:
Let
c-------> the number of cookies in each batch
we know that
To find the total number of cookies, multiply the number of batches by the number of cookies in each batch
so
------> equation that represent the total number of cookies
If Anna ate
cookies
then
The expression to know how many cookies Anna has left is equal to

Answer:
70/100
Step-by-step explanation:
Surface of the earth covered with water = 7/10
Equivalent fraction of 7/10 with 100 as the denominator = 70/100
This means 70% of the earth surface is covered with water
Percentage covered with land = Total percentage - percentage covered with water
= 100/100 - 70/100
= 100-70/100
= 30/100
Percentage covered with land = 30%
Answer:
the answer would be 28.
Step-by-step explanation:
you're multiplying the top and bottom by 7. 3 *7=21 for the bottom
4*7 = 28 for the top
Hope this helps

Answer:
The answer is letter E.
Step-by-step explanation:
If you divide the whole numbers by the fractional equivalent to the power of 0, then you would come to the conclusion that the answer cannot be "expressions", but can only be E.
