Answer:
Is a right triangle
Step-by-step explanation:
step 1
Find the measure of angle C
Remember that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
substitute the given values
therefore
The triangle is a right triangle, because has a internal angle of 90 degrees
So you're trying to find what number is like that right? Well multiply the denominator by the 20 (20*4) which equals 100, so 100-20 (the one fourth) is 80. So 3/4 fourths of 100 is 20.
Answer:
A = 143.2
Step-by-step explanation:
A= πr² = π(6.75)² = 
× 45.5625 = 143.196 ≈143.2
Answer:
-2
Step-by-step explanation:
The slope of a line is rise/run
So, just see how much the line rises/how much the line runs
In this case, the line rises 2 units for every -1 unit it runs
So, the slope is -2
