Step-by-step explanation:
sin(x)=±9/41
As x lies in Quadrant 4 , sin(x) = -9/41
Answer:
Step-by-step explanation:
VUT=VUW+WUV
and mVUW= mWUV
4x+6=6x-10
-2x=-16
x=8
mWUT=6x-10=6(8)-10=38°
Your answer is 38
We can see the ratio of a side big figure and small figure is 60:15 or 60/15 = 1/4.
In decimal form we can write 1/4 as 0.25.
Therefore, scale factor is 0.25.
So, second option is applicable. Please check second option :
<h3>The scale factor is 0.25.</h3>
Now, let us find the side A by multiplying by scale factor 0.25 of the big figure.
The corresponding side of A is 35.
Therefore, A is 0.25 × 35 = 8.75 cm.
Therefore, other applicable option is 3rd option.
<h3>The length of side A is 8.75 cm.</h3>
Answer:
∠ABC = 84°
∠CAB = 54°
Step-by-step explanation:
Assume that a point on side AB, its point F
so that, EA = FA
Then triangle AEO ≅ triangle AFO
So,
OF = OE = BF
Triangle BOF is isosceles.
∠CEO=180−∠ABC
So that,
180 − 
∠ABC + 42 = 180
Now solve for ∠ABC.
∠ABC = 84°
∠CAB = 180 - 84 - 42 = 54°
That's the final answer.
