Sagot :
Answer:
x = 41.16
Step-by-step explanation:
- The value of the top angle in the triangle is equal to 90° - 27° = 63° as they are complementary angles
- To find x, take the tan ratio of the angle
- tan63° = 1.96
- tan63° = x/21
- ⇒ x/21 = 1.96
- ⇒ x = 21 * 1.96
- ⇒ x = 41.16
Answer:
x=41.2
Step-by-step explanation:
Assuming that the dotted line and the vertical line form a 90 degree angle, we can find the angle measurements of the triangle.
Since there is a 90 degree angle formed between the dotted line and the vertical line, subtracting 27 from 90 will get us the angle measure of one of the vertex of the triangle.
90-27=63 degrees
Now we can use trig. ratios to help us figure out the missing side.
tan(63)=x/21
x=tan(63)*21
x=41.21482062
x=41.2
