Answer:
x = 52.0
Step-by-step explanation:
Reference angle = 68°
Length of side Opposite to reference angle = x
Adjacent length = 21
Apply the trigonometric function, TOA, which is given as:
Tan 68° = Opp/Adj
Substitute
Tan 68° = x/21
21 × Tan 68° = x
51.9768238 = x
x = 51.9768238 ≈ 52.0 (approximated to nearest tenth)
Answer:
D) The third side could be 4 meters long.
Step-by-step explanation:
The third side of a triangle must be greater than the difference and less than the sum of the other two sides.
5-4=1
5+4=9
So the third side must be GREATER THAN 1 and LESS THAN 9. (1<x<9)
Therefore, the answer can't be A or C. The second one <em>could </em>be correct, depending on how much less than 4 it is. But the last one is definitely correct.

➷ Since this is an isoceles triangle, you can figure it out easily.
We know that the sum of the angles is 180 degrees.
180-56=124
124/2=62
X=62

Answer:
1st, keep value of x in 1st equation
Step-by-step explanation:
-6(-2y-1)+2y=48
12y+6+2y=48
14y=48-6
y=42/14
y=3
Now putting value of y in equation ii)
x= - 2y-1
x= - 2×3-1
x= - 6-1
x= - 7
Therefore, x= - 7
y=3
Answer:
b
Step-by-step explanation:
u1 = 20
r = 5
Un = 20 × 5^(n-1)
Un = 20 × (5^n)/5
Un = 4 × 5^n
