Answer:
29
Step-by-step explanation:
x=4. 4-1=3. 7x3=21. 21+8=29. Viola
Answer:
<u>A = 61°</u>
<u>B = 72°</u>
<u>C = 47°</u>
Step-by-step explanation:
Well, first of all, we can see that:

So, we can find angle B.


Now, we can see to that angle C is just 47°
Finally, we know that the sum of all angles in a triangle is 180°, so we have:



I hope it helps you!
For this case by similarity of triangles we can use the following relationship:
(x) / (11) = (2) / (10)
We clear the value of x:
x = ((2) / (10)) * (11)
Rewriting:
x = ((1) / (5)) * (11)
x = 2.2
Equivalently:
x = 22/10
x = 11/5
Answer:
The value of x is:
x = 2.2
Equivalently:
x = 11/5
