Answer:
$13200
Step-by-step explanation:
All we have to do is set up a proportion.
1200/100=x/1100
Thathat means that
100x=1,320,000
x= 13200
Answer
angle 5 = 31°
Step-by-step explanation:
Let the starting position be A, and the ending position of the glide be B.
The triangle ABC shown in the figure, is a right triangle with side lengths 16m and 0.8 m.
The angle of the squirrel's path below the horizon is BAC.
Using right triangle trigonometry:
tan(ABC)=(opposite side)/(adjacent side)=0.8/16=0.05
to find m(ABC) we calculate arctan(0.05) which is 2.86°
Answer: 2.86°
Answer:
x = y - rd + c
Step-by-step explanation:
x - c = y -rd
x = y - rd + c
The correct answer is: Option (B) m∠a = 38°, m∠b = 52°, m∠c = 90°
Explanation:
Given measure of each angle:
m∠a = (48-x)°
m∠b = (9x-38)°
m∠c = 90°
Now, as you can see, that one angle, m∠C, of the triangle ABC is 90°; therefore, we can infer that it is a right-angled triangle.
For right-angled triangle, the sum of all the angles is 180°. We can write it mathematically as:
m∠a + m∠b + m∠c = 180° --- (1)
Plug in all the measure of angles in equation (1):
(1)=> (48-x)° + (9x-38)° + 90° = 180°
Solve to find the value of x:
8x + 100° = 180°
8x = 80°
x = 10°
Now put the value of x in all individual angles to find m∠a, m∠b, and m∠c.
m∠a = (48-10)° = 38°
m∠b = (9*10-38)° = 52°
m∠c = 90°
Hence the correct answer is Option (B).
