A triangle 45 – 45 – 90 degree (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of 1:1:√2
if hypo = 3√2 then side = 3
answer
a = b = 3
-------------------
<span>30-60-90 Triangle
</span>long leg = short leg times √3
hypo = twice the short leg
given long leg = 5√3
so
short leg = b = 5
hypo = c = 2(5) = 10
You're going to use the substitution method for this.
First, we know that Y = x-7, so we can plug x-7 into everywhere we see Y!
3x - 3(x - 7) = 21
then we simplify
3x - 3x + 21 = 21
^ ^
These cancel out!
So we're left with...
21 = 21
That means that the solution to this equation is all real numbers!
Answer:
A
Step-by-step explanation:
Let's check each one-by-one.
a.
we know 3.79 liters is 1 gallon, so 4 liters IS NOT LESS THAN 1 gallon
THis is false.
b.
We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.
This is true.
c.
we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.
THis is true.
d.
We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles
So definitely 9 miles IS GREATER than 10 km.
THis is true.
So answer choice A is false, only.
