Hi there!
Since the sum of all angles in any triangle always adds up to 180 degrees, we can calculate this and solve for x.
4x + x + x = 180°
6x = 180
180 ÷ 6 = x
x = 30
So, now we know that x is 30°.
Hope this helps!
Answer:
$360
Step-by-step explanation:
If Shelly wants 6 rose bushes, and each bush costs $40, then you can multiply 6 by 40 to find the total amount of money Shelly will spend on them if she plants them herself. 6 x 40 = 240. You can then subtract 240 from 600 to find the amount of money she saves. 600 - 240 = 360
Answer:
Angle 4=82 degrees, then i think angle 1 and 3= 98 degrees
Step-by-step explanation:
Angle 2=Angle 4 and 180-82=98
Area(A)= lw
perimeter(P)= 2w+2l= 34in
length(l)= w+5
width(w)= w
1/2 P= 17= w+l
17= w+(w+5)
17= 2w+5
2w=12
w=6 in
l= w+5
l= 6+5
l=11 in
A= lw= (11)(6)= 66in²
Answer:
Area of rectangle is 66 in².
Answer:
Part 4) 
Part 10) The angle of elevation is 
Part 11) The angle of depression is 
Part 12) 
or 
Part 13) 
or 
Step-by-step explanation:
Part 4) we have that
The angle theta lies in Quadrant II
so
The sine of angle theta is positive
Remember that
substitute the given value
Part 10)
Let
----> angle of elevation
we know that
----> opposite side angle theta divided by adjacent side angle theta
Part 11)
Let
----> angle of depression
we know that
----> opposite side angle theta divided by hypotenuse
Part 12) What is the exact value of arcsin(0.5)?
Remember that
therefore
-----> has two solutions
----> I Quadrant
or
----> II Quadrant
Part 13) What is the exact value of 
The sine is negative
so
The angle lies in Quadrant III or Quadrant IV
Remember that
therefore
----> has two solutions
----> IV Quadrant
or
----> III Quadrant
