Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relations between triangle sides and trig functions. Here, the marked sides are opposite and adjacent to the marked angle, so the relevant relation is ...
Tan = Opposite/Adjacent
tan(θ) = 29/14
To find the angle measure, we use the inverse function. It may be called tan⁻¹ on your calculator. It also goes by the name "arctangent." The term "arctan" can be thought of, or even pronounced as, "the angle whose tangent is ...".
θ = arctan(29/14) = 64.23°
The measure of angle θ is about 64°.

Additional comment
The default units for angle measure are radians in most spreadsheets and on-line calculators. You need to make sure your hand-held calculator mode is set to give angles in the units you want. Here, we've given the angle in degrees, which is usually what is expected in problems like this.

What is the area of the shaded region?
Round your final answer to the nearest hundredth.
Answers
answer: 37.7cm^2

50.27 - 12.57 = 37.7
One angle of a triangle measures 95°. The other two angles are in a ratio of 4:13. What are the measures of those two angles?
Answers
Answer:
20° and 65°
Step-by-step explanation:
180 - 95 = 85
other two angles must add up to 85°
since the ratio is 4:13, we can divide 85 by 17 and get 5
4(5) = 20
13(5) = 65

6x + 9 <7x
Answers
Answer:
x > 9
Step-by-step explanation:
6x + 9 < 7x .
-6x -6x <---- Subtract 6x from both sides.
9 < x <----- 7x - 6x = 1x (which can also be written as just x)
Therefore the answer is x > 9.

If the area of the base of a rectangular prism is 35 square feet and the volume is 175 cubic feet, what is the height of the prism?
Answers
Answer:
5 ft
Step-by-step explanation:
area = L * W * H
35 = L * W
Volume = (L *W) * H
since we have already found that L * W is already 35
175 = 35 * H
Divide by 35 on both sides to get H
175/35 = 5
answer = 5 ft

Which equation is not equivalent to 2x+14=4x−6
14+6=2x14 plus 6 is equal to 2 x
−2x=20negative 2 x is equal to 20
2x−4x=−202 x minus 4 x is equal to negative 20
x=10
Answers
Answer:
b) -2x = 20, negative 2x is equal to 20
(Because, -2x = -20)
Step-by-step explanation:
Given equation,
→ 2x + 14 = 4x - 6
Now the value of x will be,
→ 2x + 14 = 4x - 6
→ 2x - 4x = -6 - 14
→ -2x = -20
→ x = (-20)/(-2)
→ x = 20/2
→ [ x = 10 ]
Hence, the value of x is 10.

(0,-9), x = 0, (-3,0), (3,0), domain, -9
Step-by-step explanation:
Complete the square and you can read everything off the equation,
y = x^2 - 9
= (x - 0)^2 - 9
Vertex : (0,-9)
Axis of symmetry: x = 0
x-intercepts: x^2 = 9 -> x = ±3
Left x-intercept: (-3,0)
right x-intercept: (3,0)
Since the function is well-defined for any x-values,
we can say that its domain is the set of all real numbers.
Since the minimum point of the graph is (0,-9),
The range will be greater than or equal to -9.
