Tell whether the angles are complementary or supplementary. then find the value of x
2 answers:
Hello,
In Q5. Being a straight line the angles are supplementary to each other.
And x = 70°
In Q6.
The angles sum up to 90° , so 25x + 30° = 90
25x = 60°
x= 60°/25 = 2.4°
Hope this helps.
Answer:
see explanation
Step-by-step explanation:
5
x and 110 form a straight angle and are supplementary, thus
x + 110 = 180 ( subtract 110 from both sides )
x = 70
6.
25x and 30 form a right angle and are complementary, thus
25x + 30 = 90 ( subtract 30 from both sides )
25x = 60 ( divide both sides by 25 )
x =
= ![\frac{12}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B5%7D)
