Answer:

(-5/2 , 3/2)

Step-by-step explanation:

y=4+x

6(4+x) + 2x= 4

24 + 6x + 2x= 4

24 + 8x= 4

8x =4 - 24

8x=-20

x= -20/8= -5/2

y-(-5/2)=4

y+5/2= 4

multiply throughout by 2 to clear out fraction

2y + 5= 8

2y= 8-5

2y=3

y=3/2

Triangle abc is an isosceles right triangle. What is the measure of one base angle? 30ş 45ş 60ş 90ş.
alisha [4.7K]

Answer:

  45°

Step-by-step explanation:

The acute angles of a right triangle are complementary. The base angles of an isosceles triangle are congruent. If x is the measure of the base angles, this requires ...

  x = 90-x . . . . . the base angle is congruent to the other base angle

  2x = 90 . . . . . add x

  x = 90/2 = 45 . . . . divide by 2

The measure of a base angle of an isosceles right triangle is 45°.
