Answer:
C
Step-by-step explanation:
interior angle + exterior angle are supplementary
interior angle = 180° - exterior angle
⇒ interior angle = 180° - 135° = 45°
and interior angle = 180° - 100° = 80°
The sum of the 3 angles in a triangle = 180°
To find the third interior angle, subtract the sum of the 2 interior angles from 180
third interior angle = 180° - (45 + 80 )° = 180° - 125° = 55°
interior angles are 45°, 55° and 80°
The addition property of equality justifies this. You could also say that she simply subtracted 7, and then it would be the subtraction property of equality. This is the case because if you add or subtract (or multiply or divide) the same number on both sides of an equation, the equation will still be the same.
Hope it helps!
Answer:
322.63%
Step-by-step explanation:
Volume of square pyramid = 1/3a²h
a = base side length ; h = height
Volume of pyramid A :
a = 18 ; h = 9
V = 1/3*18²*9
V = 18² * 3
V = 972 in³
Volume of pyramid B = 3136 in³
Volume of pyramid B / Volume of pyramid A
(3136 / 972) * 100% = 322.63%
2.8a^2=55
a^2=55/2.8
a= square root of 55/2.8
Answer:B
Step-by-step explanation:
Given
Every student secure same average score
Standard deviation is denoted by \sigma
Consistency is criteria of acceptance then Student should be selected the standard deviation is least for student B.
Standard deviation tells how a data varies from mean Position .
More Deviation from mean indicates less consistency .
