Answer:
2(219)^1/2.
Step-by-step explanation:
876 = 2*2*3*73
√876 = 2*√219
= 2(219)^1/2.
Answer: 70
=====================================
Explanation:
The exterior angles (2x+12) and (2x) have corresponding interior angles 180-(2x+12) and 180-(2x)
Triangle ABC has the following interior angles
A = 112
B = 180 - 2x
C = 180 - (2x+12) = 180-2x-12 = 168-2x
Add up the interior angles for A,B,C and set the result equal to 180. Solve for x
A+B+C = 180
(112)+(180-2x)+(168-2x) = 180
112+180-2x+168-2x = 180
460-4x = 180
-4x = 180-460
-4x = -280
x = -280/(-4)
x = 70
---------------
Side note:
2x = 2*70 = 140 is the exterior angle for B, so 180-140 = 40 is the interior angle for angle B
2x+12 = 2*70+12 = 152 is the exterior angle for C, so 180 - 152 = 28 is the interior angle for C
Add up the interior angles to find that A+B+C = 112+40+28 = 180, so this helps confirm we have the right x value.
Answer:
To change a number from scientific notation to standard form, move the decimal point to the left (if the exponent of ten is a negative number), or to the right (if the exponent is positive). You should move the point as many times as the exponent indicates. Do not write the power of ten anymore.
HOPE THIS HELPED!!!!!!!!!!!!!XDDDDDD
