I need the smaller and larger angle

Mathematics
1 answer:
SSSSS [86.1K]3 years ago
6 0

Answer:

x=11

Step-by-step explanation:

(4x)+(3x+13)=90                

if you look at the beam, it includes a 90 degree angle.

7x+13=90

distributive property

7x=77

subtracted both sides by 13

x=11

divided both sides by 7 to isolate x

4(11)         3(11)+13

44             33+13

                36

4(x) is the larger angle

bearhunter [10]

Answer:Rosk Construction has the best work output.

Step-by-step explanation:

1. The unit rate for Rosk Construction is 62

(because a=62w)

2. The unit rate for Fosbert’s Construction is

65 (because 130/2=65; 260/4=65; &

390/6=65. Therefore the unit rate is 65).

3. The unit rate for Durable B Construction is

63 (because 63/1=63; 126/2=63; &

189/3=63. Therefore the unit rate is 63).

In the diagram, PN¯¯¯¯¯ is the perpendicular bisector of AB¯¯¯¯¯ and is also the angle bisector of ∠CPD. If m∠CPD = x, which qua
zaharov [31]

Since ∠CPD = x and segment PN is the angle bisector of this angle, therefore segment PN equally divides ∠CPD into two angles. Which means that:

∠CPN = ∠NPD = x / 2

Further, segment PN is also the perpendicular bisector of AB which further means that the intersection formed by PN and AB creates a right angle (90°). Therefore:

∠NPD + ∠DPB = 90°

x/2 + ∠DPB = 90°

∠DPB = 90 – x/2

Therefore:

sin∠<span>DPB = sin(90 – x/2) which is not in the choices</span>

However we know that the relationship of sin and cos is:

sin(π/2 - θ) = cos θ

Where,

π/2 = 90

θ = x/2

Therefore:

sin(90 – x/2) = cos(x/2)

 

Answer:

<span>cos(x/2)</span>
