Answer:
2.97×10³
Step-by-step explanation:
3600 - 6.3×10² = 3600 -6.3×100 = 3600 -630 = 2970
= 2.97×1000
= 2.97×10³

Answer:
x = 45°
Step-by-step explanation:
"Isosceles" means the base angles are congruent: they both have the same measure, 45°. (The hypotenuse is the "base" for this isosceles triangle.)
The acute angles of a right triangle are complementary, so the third angle can also be found as 90° -45° = 45°.
Answer:
The answer is s = 1.
Step-by-step explanation:
Opposite sides of a parallelogram are equal so,
3s + 19 = s + 21
3s - s = 21 - 19
2s = 2
s = 1
next,
s + 21 =? 3s + 19
1 + 21 equal to (?) 3(1) + 19
22 = 22
so the answer is correct
