Answer:
Find the value of x in each of the given figures.
Step by step explanation :
a. .. Let the triangle be ABC
we have to find the value of A
so
ATTQ ( According to the question) we have ::
B = 25°
C = 105° + ___ = 180° ( adjacent angles)
C = 75 ° = 180° - 105° ( transfer 105° from LHS to RHS)
The sum of all interior angles of a triangle is 180° .
so, A+B+C = 180°
A+ 25° + 75° = 180°
A+ 100° = 180°
A= 180° - 100°
A = 80°
therefore answer is 80°
b. .. Let the triangle be ABC.
we have to find the value of x
ATTQ , we have
A= 3x+2°
B=2x°
C = 152° + ___ = 180°
C= 180°- 152° = 28°
The sum of all interior angles of triangle is 180°
so, A+B+C = 180°
3x+2° + 2x° + 28° = 180°
first add the variables then numbers
5x° + 30° = 180°
5x° = 180° - 30°
5x ° = 150°
x° = 150° / 5
x = 30°
therefore answer is 30°

Answer:
856.05
Step-by-step explanation:
Your answers would be
D) 13 in, 84 in, 85 in
A) 7.5
C) 28.3 cm
Use the quadratic formula to solve it:
<span>Y= -6x^2 +100x -180
a= -6
b= 100
c= -180
x = [-b +- sq root(b^2 - 4ac)] / 2a
x = [-100 +- sq root (10,000 -4*-6*-180)] / -12
x = [-100 +- </span><span>sq root (10,000 -4,320)] / -12
