Answer:
<2 = 35degrees
<3 = 55degrees
Step-by-step explanation:
Find the diagram attached:
From the diagram:
<3 + <4 = 90
<3 + 35 = 90
<3 = 90 - 35
<3 = 55degrees
Also m<1 + m<2+ m<3 = 180 (sum of angles in a traingle)
90+<2+55=180
145+<2 = 180
<2 = 180 - 145
<2 = 35degrees
Answer:
y = 3n + 70 - 35 or y = 3n + 35
Step-by-step explanation:
you get 3n bc she gets 3 rocks per hike(n)
you get 70 - 35 or just 35 bc she started with 70 then gave half away and half of 70 is 35
Answer:
B
Step-by-step explanation:
Note that i² = - 1
Given
(4 - 2i)(1 + 7i) ← expand factors using FOIL
= 4 + 28i - 2i - 14i²
= 4 + 26i + 14
= 18 + 26i → B
