The measure of ∠DCB is 128°.
The measure of ∠ECD is 52°
<u>Step-by-step explanation</u>:
- At the point of intersection, the opposite angles are equal.
- Therefore, ∠ACB = ∠ECD and ∠ACE = ∠DCB
- The measure of angle in straight line is 180°.
∠ACB + ∠ACE = 180°
(x+11)° + (3x+5)° = 180
⇒ 4x+16 = 180
⇒ 4x = 164
⇒ x = 164/4
x = 41°
∠DCB = ∠ACE ⇒ (3x+5)°
∠DCB = 3(41)+5 = 128°
∠ECD =∠ACB ⇒ (x+11)°
∠ECD = 41+11 = 52°
so hmm whatever "p" and "c" are, we know that
p + c = 10.
and we also know that
3p + 2.2c = 25thus
how much will it be needed for caramel popcorn? well, c = 10 - p.
Answer:
A. 60°
Step-by-step explanation:
3tan^3 x= tan x
3tan^2x = 1
tan^2 x = 1/3
tan x = 1/
x = 60°
Answer:
9.8 units
Step-by-step explanation:
distance = sqrt (x2 - x1)^2 + ( y2 - y1)^2
sqrt (-3 - (-6))^2 + (5 - 1)^2
sqrt (9)^2 + (4)^2
sqrt 81 + 16
sqrt 97
