Answer:
w=59 y=59 z=53 x=121 v=121
Step-by-step explanation:
inside a triangle the angles should add up to 180 so you can easily do 180-31 -90 to find w then with that you can find the rest and also w is equal to y cause theyre vertical angles
Answer:
Step-by-step explanation:
<em>Refer to attached picture</em>
- The height = h
- Angles of elevation 22.6° and 38.3°
- Closer distance = d
<u>Use tangent to solve</u>
- tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)
- tan 38.3° = h/d ⇒ h = d tan 38.3° ⇒ h = 0.79d
<u>Compare the equations above and find the value of d:</u>
- 0.42(d + 17) = 0.79d
- 0.42d + 7.14 = 0.79d
- 0.79d - 0.42d = 7.14
- 0.37 d = 7.14
- d = 7.14/0.37
- d = 19.3 m
<u>Now find the value of h:</u>
- h = 0.79d
- h = 0.79*19.3
- h = 15

He is wrong...
2 1/2 + 3 3/5 = 97/20
Simplified, I believe the answer is 4 17/20
We have the expressions:




Now, with this we operate as follows:
a)


Then, the axis is x = -3 and the vertex (-3, 6)
b)


Then, the vertex is (2, 5) and the axis is x = 2.
c)

Then, the vertex is (2, -4) andd the axis is x = 2.
d)


Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
