Answer:
7³
Step-by-step explanation:
You could answer this after a quick inspection. 7 remains constant as t approaches 8. Each of the (t -1) terms will approach 7. So, multiplying these factors together, you'll get 7(7)(7) = 7³3 as your answer, the limit as t approaches 8 of the given expression.
Less than 90° = acute
more than 90° = obtuse
equal to 180° = straight
more than 360° = reflex
The decimal adds a zero every time the powers of ten increase for example if u do 1 x

=100 if u do 1x

=1,000
