90-70= 20
angle 4= 20
90-50= 40
angle 6= 40
90-15= 75
angle 8= 75
For the given triangle, the tan of angle A equals 
Step-by-step explanation:
Step 1:
In the given triangle for angle A, the opposite side has a length of 6 cm, the adjacent side has a length of 8 cm while the hypotenuse of the triangle measures 10 cm. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

Step 2:
The opposite side's length = 6 cm.
The adjacent side's length = 8 cm.

Answer:
162
Step-by-step explanation:
Given algebraic expression:
To:
- Evaluate this expression,with : x = 6
Solution:
Simplify by plugging x = 6
- 4(6)²+3(6)
- 4(36) + 18
- 144 + 18
- 162
<em>We can conclude:</em>
By evaluating this expression by x = 6 , the answer will be 162.
Question
:
