Answer:
X = 55°
Step-by-step explanation:
You can tell if a pair of angles, in this case, is 90° if you see the red box in the corner of the angle.
The pair of angles in the picture are complementary angles, which add up to 90°. Therefore, subtract 35 from 90 to find the value of X which is 55°.

If we use the place value chart, 10020 and 20010 will be further dissected based on place values. At first look, 20010 seems to have more tens and that is fact; but this method will show us that it is otherwise so follow the solution below carefully:
Employing PLACE VALUE CHART:
For 20010:
*10000 <--- Ten-thousands place.
*10000 <--- Ten-thousands place.
*10 <--- Tens place.
Add these numbers and you will get: 20010. 20010 has two ten-thousands place and one tens place.
For 10020
*10000 <--- Tens-thousands place.
*10 <--- Tens place.
*10 <--- Tens place.
Add these numbers and you will get: 10020. 10020 has one ten-thousands place and two tens place.
Therefore, there are more tens in 10020 than in 20010.
Answer:
the number is 20
Step-by-step explanation:
6% of x = 20% of 6
0.06x=0.20*6
0.06x=1.20
x=1.20/0.06
x=20

Answer:
30°
Step-by-step explanation:
The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:
Sin = Opposite/Hypotenuse
For a ramp 1 m high and 2 m long, we have ...
sin(x) = (1 m)/(2 m) = 1/2
x = arcsin(1/2) = 30°
The elevation angle of the ramp needs to be 30°.
