Answer:
-1/cd
b = -a/cd
Step-by-step explanation:
a = -bcd
Multiplication and division are inverse operations
Multiply each side by -1/cd
a* -1/cd = -bcd * -1/cd
-a /cd = b
4) 121 degrees
because if x is 121 degrees then angle BCA will equal 59 degrees (the two angles must equal 180) so using the sum of a triangle's angles, then angle BAC will have to equal 59, making the triangle an isoceles, which will make AB to be congruent to BC.
Answer:
c 4.1 inches
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
The sector is only 78 degrees
Take the fraction of a circle and multiply by the circumference to find the length x
x = C* 78/360
= 2 * pi *r * 78/360
= 2 * pi *3 * 78/360
Using 3.14 for pi
= 4.082
Rounding to the nearest tenth
x = 4.1 inches
