Answer:
x=79*
Step-by-step explanation:
136+60+85+x=360
281+x=360
x=360-281
x=79
Answer:
x = 74°
Step-by-step explanation:
The diagram shown in this question, is a Quadrilateral inscribed in a circle
It is important to note that
The sum of opposite angles in a Quadrilateral = 180°
93° + z = 180°
z = 180° - 93°
z = 87°
In a cyclic quadrilateral,
Intercepted angle = 1/2(Intercepted arc)
Intercepted angle = 93°
Intercepted arc = x + 112°
Hence,
93° = 1/2(x + 112)°
93° × 2 = x + 112°
186° = x + 112°
x = 186° - 112°
x = 74°
All you have to do, is combine like terms. Let's go through it:
Arrange it so you can easily combine like terms:
So, your answer for the sum is 1) 7x² - 10x + 2
