Answer:
1. B = 42° C = 138°
2. ∠S = 28°
Step-by-step explanation:
1. Since b and 42° are across from each other, they are congruent angles. So, b would equal 42°. We still don't know the value of c, we can do 42 + 42 + 2c = 360, because again, the two angles are across from each other. The whole equation equals to 360 because the intersecting lines kind of forms a circle and a circle is 360°.
2. All the angles of a triangle add up to 180°. Since the triangle is a right triangle, we know 2 out of the 3 angles. The equation would then be, 62 + 90 + s = 180.
Answer:
-951
Step-by-step explanation:
an=a1+(n−1)d
\begin{gathered}29 = a_1 + (1-1)d\\29 = a_1\\9 = 29 + (2-1)d\\9 = 29 + d\\d = -20\\a_n = 29 -20 (n-1)\\a_n = 29 - 20n+20\\a_n = -20n + 49\\\\a_51 = -20(51) + 49 = -951\end{gathered}29=a1+(1−1)d29=a19=29+(2−1)d9=29+dd=−20an=29−20(n−1)an=29−20n+20an=−20n+49a51=−20(51)+49=−951
