in right angle traingle two angle are equal
so.x=y
in triangle
x+y+90=180(sum of interior angle of triangle)
2x=180-90
x=90/3=45°
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Step-by-step explanation: I'm taking the test
B) 65.
A^2 + B^2 = C^2 so C^2 - B^2 = A^2.
C^2 = 97^2 which is 9,409
B^2 = 72^2 which is 5,184
9,409 - 5,184 = 4,225
Square root of 4,225 is 65.
5 amplifiers in 30 minutes is the same as 10 amplifiers per hour. Divide 230 amplifiers by 10 amplifiers (which is how many you can make per hour) to get 23 hours [the answer].
