Answer:
49/4
Step-by-step explanation:
x² -7x +(7/2)²=(x-7/2)²
x²-2x·7/2+ (7/2)²=(x²-7/2)²
(7/2)²=49/4
Answer:
tan theta = 8/15
Step-by-step explanation:
Sin is equal to opposite over hypotenuse. So it means that the side opposite from theta is 8, and the hypotenuse is 17.
To find the value of the adjacent side from theta, use the Pythagorean Theorem.
a^2 + b^2 = c^2
8^2 + b^2 = 17^2
64 + b^2 = 289
Subtract 64.
b^2 = 225
Take the square root.
b = 15.
So that means:
the side opposite from theta is 8,
the side adjacent from theta is 15,
the hypotenuse is 17.
Now we take tan, opposite over adjacent, and use the values from the triangle.
tan = opposite / adjacent
tan = 8/15.

Answer:5:15
Step-by-step explanation:
2:30+2 hour=4:30
4:30+45=5:15
Answer:
• Group the h terms by organised term arrangement :
• Then using distributive property, factorise out the value h so that the reverse is true.
• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:
• finally, completely factorise out the value h
