We know that since a diameter splits a circle in half, the arcs EF, FG, and GH must add up to 180°, half the measure of a full circle. We can then use the arc addition property to create an equation using the information we know. This equation would be (10x + 8) + 67 + 11x = 180. This can be simplified to x = 5. Therefore, the value of x is 5. Now, we can simply plug in the value of x into the expressions for EF and GH. This means that the measure of EF is 58° and the measure of GH is 55°.
Hope this helps!
The correct answer should be 95. I don’t know how you did it but try the PEMDAS method (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
do 6 - 15 and the answer of that will be n which is 9
Start with 1/5x – 2/3y = 30. Let y = 15: (<span>1/5)x – (2/3)(15) = 30
Then (1/5)x - 10 = 30, and (1/5)x = 40, and so x = 200 (answer)</span>
