17) let the unknown be x.
tanx = 3.5
x = tan⁻¹(3.5) use your calculator
x ≈ 74.05° x ≈ 74.1 to the nearest tenth
18)
tan 34 = x/20
20*tan34 = x
20*(0.6745) ≈ x
13.49 ≈x
x ≈ 13.49 x ≈ 13.5 to the nearest tenth
19) tan2° = 2/x
x = 2/tan2°
x = 2/0.0349
x ≈57.31 x ≈ 57.31 to the nearest tenth
20) tanx = 90
x = tan⁻¹(90) Use your calculator
x ≈ 89.36°
x ≈ 89.4° to the nearest tenth.
Answer: 1/4
Explanation: Slope formula is (y1-y2)/(x1-x2)
Just plug in those numbers from the data points and you will get your answer.
-26-(-32) = 6
-37-(-61) = 24
6/24 = 1/4
Answer:
Yes, the expressions are equivalent
Step-by-step explanation:
Let's check it out:
=> -3x(5-4)+3(x-6)
Expanding brackets using distributive property.
=> -15x+12+3x-18
Combining like terms
=> -15x+3x+12-18
=> -12x-6
Yes, the expression is equivalent to -12x-6
The value of x° + y° is 216°
<h3>How to determine the angles</h3>
Note that the shape is a regular pentagon
Sum of angle in a pentagon = 540
Angle on each side = 108°
x = 108°
y = 108°
x° + y° = 108 + 108
x° + y° = 216°
Thus, the value of x° + y° is 216°
