Answer:
Acute
Step-by-step explanation:
it is not a right angle, that's 90
not obtuse, above 90
So acute less than 90
When you convert you divide i do believe
The measure of angle 3 is 90
Step-by-step explanation:
(1 - cos²A) (1 + tan²A) = tan²A
(sin²A)(sec²A) = tan²A
(sin²A)(1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → <u>Proved</u>
Answer:
$3 per notebook.
Step-by-step explanation:
i would start by taking the two notebooks away from the imaginary cart.
then a $30 backpack=10 notebooks.
if so, then, each notebook=$3 because 3x10=30.
if you re-add the two other notebooks then it would be twelve $3 notebooks=$36 ($30 backpack and two $3 notebooks) and 12x3=36 and 36=36
