Answer:
75
Step-by-step explanation:
Angles in a triangle add up to equal 180
That being said we can find the missing angle by subtracting the measures of the given angles from 180
Thus missing angle = 180 - 34 - 71
180 - 34 - 71 = 75
Which means that the missing angle = 75
Answer:
153
Step-by-step explanation:
The result is

−
16
The reason is the following:
The problem is an example of a notable product: "the sum multiplied by the diference is equal to the difference of squares", that is to say:
(
a
+
b
)
⋅
(
a
−

)
=

.
By applying this to our question, we obtain that:
(

Answer:
x = -4/5
Step-by-step explanation:
(5x - 2)2 = 10
2(5x - 2) = 10
2 * 5x = 10x
2 * -2 = -4
5x - 4 = 10x
+4 +4
5x = 10x + 4
-10x -10x
-5x = 4

-5 -5
x = -4/5
