Answer:
I believe Deductive Reasoning. Based on logic. for example, If all up-and-coming freshmen are required to take a placement test, and you're an upcoming freshmen, therefore, you have to take a placement test.
Step-by-step explanation:
Answer:
1.32
Step-by-step explanation:
Consider ...
x = sec⁻¹(4) . . . . . the inverse secant function of 4, also written arcsec(4)*
Taking the secant of both sides, we have ...
sec(x) = 4
Writing this in terms of more familiar functions, it is ...
1/cos(x) = 4
cos(x) = 1/4
Now, we can use a calculator to find the inverse function. Be sure the calculator is in the appropriate angle mode. We suspect the desired result is in radians.
x = cos⁻¹(1/4) ≈ 1.318116
sec⁻¹(4) ≈ 1.32 . . . . . radians
_____
* One way to read this is "the angle whose secant is 4." This helps remind you that the result is an angle, so can be in degrees or radians (or any of several other angle measures).
Answer:
0
Step-by-step explanation:
11-10 is 1, and 10 -10 is 0, and then 1×0 is automatically 0by default
Answer:
angle FXG is congruent to angle IXJ or JXI. GHI is 81°
Step-by-step explanation:
Angle FXG is congruent to angle IXJ because the two are vertical angles. (Vertical angle theorem)
FXG + GXH = FXH
Substitute the given values given:
49 ° + GXH = 130°
Subtract 49 both sides
49 - 49 + GXH = 130 - 49
GXH = 81°
