Answer:
cos(A)=sin(26.57°)=0.447
Step-by-step explanation:
we know that
In the right triangle ABC
The angle A and the angle C are complementary angles
so
∠A+∠C=90°
therefore
cos(A)=sin(C) -------> by complementary angles
we have
C=26.57°
sin(26.57°)= 0.447
Hence
cos(A)=sin(26.57°)=0.447

Answer:
The number of integers that can't be expressed as a difference between the squares of two integers is 250.
Step-by-step explanation:
Answer:
x = 10
y = 1
DE = 7
AC = 14
Step-by-step explanation:
x + 2 = 24/2
x = 12 - 2
x = 10
y + 6 = x - 3
y = 10 - 3 - 6
y = 1
Y= 3/8+2
This is the answer because in the equation 8y-3x+16 you would re-write it as 8y=3x+16 but to write it in slope-intercept form, you need to get the 8 away from the y. To do this you divide y by everything; creating y=3/8x+2 ( slope intercept form).
