Answer:
A. x = 11
Step-by-step explanation:
so, the angle D corresponds to angle T.
therefore, the side BD corresponds to RT.
and CD to ST.
since both triangles are similar, they must have the same angles, and all corresponding sides and other lengths must have the same scaling factor.
so,
RT × f = BD
and the same f must then apply to
ST × f = CD
21 × f = 98
f = 98/21 = 14/3 = 4.666666666...
33 × 14/3 = 15x - 11
11 × 14 = 15x - 11
154 = 15x - 11
15x = 165
x = 11
Answer:
80 signatures if he want it done in 6 weeks
96 signatures if he want it done in 5 weeks
120 signatures if he want it done in 4 weeks
160 signatures if he want it done in 3 weeks
240 signatures if he want it done in 2 weeks
480 signatures if he want it done in 1 week.
Step-by-step explanation:
1,000 - 520 = 480
All possible number depending on how many weeks he wants to spend getting signatures.
480/6 = 80
480/5 = 96
480/4 = 120
480/3 = 160
480/2 = 240
480/1 = 480
Complementary angles total 90°.
∠A + ∠B = 90°
∠A + 60° = 90° . . . . substitute the given information
∠A = 30° . . . . . . . . . subtract 60° from both sides of the equation
The angle that is complementary to ∠B measures 30°.
Answer:
y =
Domain = [3, infinity)
Step-by-step explanation:
x = 3y^2 + 3
3y^2 = x - 3
y^2 = (x-3)/3
y =
P = 2L + 2W
L = 7
W = 5
P= ???
P = 2*7 + 2*5
P = 14 + 10
P = 24 feet of lace.
