Answer:
90°
Step-by-step explanation:
sum the parts of the ratio 2 + 6 + 8 = 16
The sum of the 3 angles in a triangle = 180°
divide 180 by 16 to find the value of one part of the ratio.
= 11.25° ← 1 part of the ratio
8 parts = 8 × 11.25° = 90°
The largest angle in the triangle is 90°
The slope is 4/3 the unit rate is 1
Answer:
x = 50
R = $2500
Step-by-step explanation:
Given in the question a quadratic equation,
−x² + 100x
To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x
The value of -b/2a tells you the value x of the vertex of the function
−x² + 100x
here a = -1
b = 100
Selling price = -(100)/2(-1)
= 50
R = −(50)² + 100(50)
= 2500
9×18 rectangle plus a (18-6-6)×4 right triangle
