11. Find the coordinates of the point located six units behind the yz- plane, seven units to the right of the xz - plane, and ei
Alexxandr [17]

Answer: I think

Step-by-step explanation:Let the coordinate of the point be (x,y,z). Since the point is located 3 units behind the YZ− plane, 4 units to the right of XZ− plane and 5 units above the XY−plane ,x=−3,y=4 and z=5 Hence, coordinates of the required points are (−3,4,5)

Shalnov [3]

Answer:

C. Angle G is congruent to Angle T.

What is x^2=8x-35? Solve equation.
lilavasa [31]
               x² = 8x - 35
x² - 8x + 35 = 0
x = -(-8) ± √(-8)² - 4(1)(35)
                    2(1)
x = 8 ± √64 - 140
                2
x = 8 ± √-76
            2
x = -8 ± 4i√19
            2
x = -4 ± 2i√19

If isosceles triangle ABC has a 130° angle at vertex B, which statement must be true?
FinnZ [79.3K]

Answer:

m∠A = 25° and m∠C = 25°

Step-by-step explanation:

The sum of all three angles in a triangle must add up to 180°.  Since the measure of angle B is 130°, the sum of the other two angles have to be 50°.  

Also, the triangle is isosceles, meaning two of the sides are equal in length.  For those sides, their corresponding angles must also be equivalent.  In this case, it's the two smaller angles.  Since we have 50° between the two angles, A and C, divide 50 by 2 to get 25° for both angle measurements.
