Answer:

ABD = 36

DBC = 54

Step-by-step explanation:

The three angles form a straight line so they add to 180

2x + 3x +90 = 180

Combine like terms

5x+90 =180

Subtract 90 from each side

5x+90-90=180-90

5x= 90

divide each side by 5

5x/5 = 90/5

x =18

ABD = 2x = 2*18 = 36

DBC = 3x = 3*18 =54

A 70-foot wire attached to the top of a building is anchored to the ground 20 feet from the base of the building. Which value is

JulijaS [17]

Answer:

The the angle which the wire make with the ground is 1.280 radian .

Step-by-step explanation:

Given as :

The length of the wire attached to the top of building = OB = 70 foot

The distance of wire anchored from base of ground = OA = 20 feet

Let the angle made by wire en and ground = Ф

Now from , In Triangle AOB

Cos angle = $\dfrac{\textrm Base}{\textrm Hypotenuse}$

Or, Cos Ф = $\dfrac{\textrm OA}{\textrm OB}$

or, Cos Ф = $\dfrac{\textrm 20}{\textrm 70}$

Or, Cos Ф = $\dfrac{\textrm 2}{\textrm 7}$

∴ Ф = $Cos^{-1}(\frac{2}{7})$

I.e Ф = 73.39°

Now in radian ,

∵ 180° = $\pi$ radian

∴ 73.39° = $\frac{\pi }{180}$ × 73.39°

= $\frac{3.14 }{180}$ × 73.39° = 1.280 radian

Hence The the angle which the wire make with the ground is 1.280 radian . Answer

Using coupons, you spend $135 grocery shopping. this is 75% of the total retail price of the groceries. how much would you have

Usimov [2.4K]

Let x be the total price. And you paid 75% of it which is $135.

x * 75/100 = 135
x = 180
You would have paid $180 if you had not used coupons.

Answer:

$\triangle ABC \cong \triangle DCB$ by AAS

Step-by-step explanation:

According to the following two triangles, $\triangle ABC$ and $\triangle DCB$ are congruent by Angle-Angle-Side (AAS), because there are two angles shown and share a side, which is in the middle between triangles.
