Answer:

D = 127°

Step-by-step explanation:

We know that sum of all angles in a triangle is 180°.

Thus, the measure of third angle will be -

180 - (85 + 42)

180 - 127

= 53°

We also know that sum of adjacent angles is 180°. So,

D = 180° - third angle

D = 180° - 53°

D = 127°

Answer:

∠ D = 127°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ D is an exterior angle of the triangle , then

∠ D = 85° + 42° = 127°

Kalei is 6ft tall and stands 10 feet from a tree. He measures an angle if elevation of 30° up to the coconuts on the tree. How h
Juli2301 [7.4K]

Answer:

The total height of coconut Tree = H + 10ft = 11.77 ft

Step-by-step explanation:

Given as,

The height of Kalei = 6ft

The distance of Kalei from the coconut Tree = 10 feet

Angle of elevation of kalei up to the coconut on tree = 30°

<u>Note : look at the pic attache </u>

From figure it is mention that

Total height of Tree = 6 ft + H

So, Tan 30° = \frac{perpendicular}{base}

     Tan 30° = \frac{H}{10}

    ∴ H         = 10 Tan 30° = 10 × 0.577         Note : tan 30° = 0.577

i.e    H         = 5.77 ft

Hence the total height of coconut tree = 6 + 5.77 = 11.77 ft   Answer

Please help and thank you! Will mark whoever answers right the brainliest!
laila [671]

Answer:

Step-by-step explanation:

Part A. John will not be painting the floor area of that of the door or window openings.

Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.

Part C.

We first need to find the area to be painted.

A=floor+2(wall1)+2(wall2)-window-door

A=14(7)+2(7)8+2(14)8-3(6)-3(7)

A=98+112+224-18-21

A=395 ft^2

Since a gallon of paint will cover 350 ft^2

395ft^2(gal/350ft^2)=1.13 gal

John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)
