Well we know that the 9.0 meter ladder is the hypotenuse And it is a right triangle with base of 1.5 meters. we have the adjacent and the hypotenuse. which is cosine. So:
cos (a) = adjacent/hypotenuse
cos (a) = 1.5/9.0
cos (a) = 1 / 6
a = cos^-1 (1 / 6)
a = 80.4 degrees
Answer:
<h2>
x = 85° </h2>
Step-by-step explanation:
m∠ADC = 180° - 95° {a straight angle}
m∠ABC = 180° - x {a straight angle}
m∠ADC + m∠ABC = 180° {a quadrilateral inscribed in a circle}
180 - 95° + 180 - x = 180°
85° - x = 0
<u>x = 85° </u>
Answer: 90.2
Reasoning: You add all grades together. Next you dived by 5 because their are 5 grades. You then revive an average of 90.2
Answer:
The inequality range of X is determined as 5 < X < 9
Step-by-step explanation:
Given;
first length of the triangle = 2 inches
second length of the triangle = 7 inches
third length of the triangle = X
From the third length rule of a triangle, the following inequality range will be applied to determine the length of "X";
The third length of the triangle must be greater than the difference of the two known sides BUT less than the sum of the two known sides.
(7 - 2) < X < (7 + 2)
5 < X < 9
possible values of X = 6, 7, 8
Therefore, the inequality range of X is determined as 5 < X < 9
