Answer:
The total cost of the meal is $38.23
Step-by-step explanation:
To find out the tax, you multiply $29.99 times .0625. The tax is 1.87
The total before the tip is $31.86
To find out the tip, you do 31.86 minus 20%. The amount is $6.37
Then you add $31.86 and $6.37 together to get $38.23
The measure of each base angle will be 50 degrees.
An isosceles triangle is a triangle where two sides are equal to each other which also makes the angles opposite them equal to each other.
The other side that is not congruent is called the base and the angle opposite that is called the vertex angle.
Given that an isosceles triangle, with a vertex angle of 80 degrees we need to find the base angles.
So the base angles in an isosceles triangle are equal, so using the angle sum property of a triangle, we get,
2 × base angles = 180° - 80°
2 × base angles = 100°
base angles = 50°
Hence the measure of each base angle will be 50 degrees.
