Answer:
1. The
is between 3 and 4.
2. The
is between 7 and 8.
3. The
is between 4 and 5.
4. The
is between 9 and 10.
5. The
is between 6 and 7.
Step-by-step explanation:
1.
: 10 is near the perfect squares 9 and 16, which would mean its answer is between their square roots which are 3 and 4.
2.
: 10 is near the perfect squares 49 and 64, which would mean its answer is between their square roots which are 7 and 8.
3.
: 10 is near the perfect squares 16 and 25, which would mean its answer is between their square roots which are 4 and 5.
4.
: 10 is near the perfect squares 81 and 100, which would mean its answer is between their square roots which are 9 and 10.
5.
: 10 is near the perfect squares 36 and 49, which would mean its answer is between their square roots which are 6 and 7.
You answer on question 13 is 350
It’s 20 degrees because all triangles are all equal up to 180° and so if you add 135° to 25° you get 160° and so minus 160 from 180 and you’ll get 20°
