So those to angles added together equals 180° thus all you have to add those together and set it equal to 180 to find hat x equals, and then add 89 to it to find the highlighted angle.
x+109+x+89=180
add the numbers and x's together
2x+198=180
subtract 198 from each side
2x = -18
divide each side by 2
x = -9
Put -9 in for x in the equation x+89 to find that angle
-9+89
=80
ANSWER:
That angle equals 80°
Answer:
the answer is 3
Step-by-step explanation:
The equation that model a quadratic function is: y=0.9673x²-0.8475x+10.4334
Step-by-step explanation:
A quadratic function has the form of ;
f(x) = ax²+bx+c where a, b and c are real numbers and a≠0
For this case, equation y=0.9673x²-0.8475x+10.4334 models a quadratic function where a>0 thus the parabola opens upwards
