The place value 8 in 281,480,100 is the 10th. And it is the same way in the other problem. How you get your answer is by counting like this EX: 1, 10, 100, 1,000, 10,000, 100,000... And so on.
Answer:
347
Step-by-step explanation:
2(3) + 210 = 216
2(3) + 125 = 131
216+131 = 347
For the given triangle, the value of x equals 30.9892 units.
Step-by-step explanation:
Step 1:
In the triangle, the angle is 40°, the opposite side has a length of 26 units, the adjacent side has a length of x units while the hypotenuse is not given.
To determine the value of x, we determine the value of the tan of the given triangle.
To calculate the tan of angle A we divide the opposite side's length by the the adjacent side's length.

Step 2:
The length of the opposite side = 26 units.
The length of the adjacent side = x units.


So x measures 30.9892 units.
First calculate

.

We take positive value of sinθ because 0° < θ < 90°
Now we could calculate sin2θ, cos2θ and tan2θ:
