Answer:
x = 16
Step-by-step explanation:
The sum of measures of these three angles of any triangle is equal to 180 °
54 + 90 + (2x + 4) = 180
144 + 2x + 4 = 180
148 + 2x = 180
2x = 180 - 148
2x = 32
Answer:
The answer is 181
Step-by-step explanation:
PEDMAS
1 x 1 + 9 x 20
1 x 1 = 1
1 + 9 x 20
9 x 20= 180
1+180
which equals 181
The formula for quadratic equation is given by:
x² - (sum)x + (product) = 0
so if we have real roots of 3 and 5
<span> x² - (3 + 5)x + (3*5) = 0
</span> x² - 8<span>x + 15 = 0
</span>
so if we have real roots of -3 and -6
<span> x² - (-3 - 6)x + (-2*-6) = 0
</span> x² - (-9<span>x) + 12 = 0
</span> x² + 9<span>x + 12 = 0</span>
30 plus EF = 180
Ef = 150
circumscribed angle plus the central angle is 180
