Answer:
x < -22/9
Step-by-step explanation:
(-9x/11) - 7 < -5 (add 7 to both sides)
(-9x/11) < -5 + 7
-9x/11 < 2 (multiply both sides by 11)
-9x < 2(11)
-9x < 22 (divide both sides by -9)
x < -22/9 (answer)
edit: typos galore!
Answer:
x = 19
Step-by-step explanation:
(5x + 4)° + (x - 2)° + (3x + 7)° = 180°
(5x + x + 3x)° + (4 - 2 + 7)° = 180°
9x° + 9° = 180° → ÷9
x + 1 = 20
x = 20 - 1
x = 19
<u>Answer:</u>
An obtuse triangle has two angles 45 and 18. The value of the unknown angle is 
<u>Solution:</u>
Given that two angles of an obtuse triangle is 45 and 18.
Third angle is θ
We are asked to find the value of third unknown angle theta
According to <em>angle sum property of triangle</em>, sum of three angles of triangle is 
This means in our case sum of 45, 18 and θ should be
Hence value of unknown third angle of an obtuse triangle is
