Answer:
6cm square
Step-by-step explanation:
(Btw that’s not 50 points, imma solve this for you because you’re desperate)
Using the Pythagorean theorem:
c^2 = a^2 + b^2
c^2 = 4^2 + 7^2
c^2 = 16 + 49
c^2 = 65
c = 8.1
Answer:
(- 4, 2 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y )→ (x, - y ), thus
(- 4, - 2 ) → (- 4, 2 )

Answer:
43
Step-by-step explanation:
x° is common to both the smaller and the larger triangle, which means the sum of the two other angles will be the same in the two triangles:
76° +49° = y° +81°
124° -81° = y° = 43° . . . . . subtract 81°
