Answer:
x=127
Step-by-step explanation:
total sum of all angle of triangle is 180 degree
Now,
taking angle A let interior angle be Y
taking angle C let interior angle be Z
Again, In angle A
the sum of interior angle and exterior angle is 180 degree being staright line
Or, y+(x+5)=180
or,x+y=180-5
or, x+y=175
or,y=175-x --------eqn 1
In angle C
the sum of interior angle and exterior angle is 180 degree being staright line
or, x+z=180
or, z=180-x ----------eqn2
Again, In triangle ABC
total sum of all angle of triangle is 180 degree.
Angle A+ Angle B + AngleC=180
Or, y+79+z=180 -------eqn3
putting the value of eqn-1 and eqn-2 in eqn-3
Or, 175-x+79+180-x=180
Or, 431-180= 2x
Or, 254÷2=x
hence X= 127 degree
Answer:
t = 7 • ± √2 = ± 9.8995
Step-by-step explanation:
To do this you must divide the two numbers -23÷45 is -0.511111....
Answer:
x = 12 y = 24 z = 12
Step-by-step explanation:
you are correct. x = 12
The dotted line has a length of 12 also
The dotted line is the shorter leg of the 30-60-90 triangle.
So, z = 12 and y = 24
The tangent ratio of ∠A is
