Answer:
Draw a picture of this. If the grade is 10.5 degrees, then the value of the angle is 90 - 10.5 = 79.5.
The length of this side, the hypotenuse, is 4
The base angle is 90.
therefore, the third angle is 10.5.
Step-by-step explanation:
It is 1.18 to 2 decimal places. (i just typed it into a calculator lol)
So all you have to do is multiply 400 times 400 which is 160,000 and divide 169,000 to 2 which is 80,000
In expanded form, 208,000,478 is:
200,000,000+8.000,000+400+70+8
The correct answers are B. (0,3) and C. (2,3/16)
Hope I helped.
