Answer:
425
Step-by-step explanation:
Answer:
43°
Step-by-step explanation:
For triangle ABC:
A = C so all we need to do is to calculate the value of B
The measure of angle ABD is given as 17° so the measure of angle EBC must be 17° as well
Since DBE is an equilateral triangle angle is DBE = 60°
17 + 17 + 60 = 94 this is the measure of angle B
The sum of interior angles in a triangle is equal to 180
A + B + C = 180
A + C + 94 = 180
A + C = 86 since A = C we divide 86 by 2
C = 43°
Answer:
162
Step-by-step explanation:
260/2=130
130+32=162
Answer:
Yes. It is an arithmetic sequence.
Step-by-step explanation:
The sequence would be add 5 every time.
-9 + 5 = -4
-4 + 5 = 1
1 + 5 = 6
