A tree is standing behind a building. 2/5th of the height of the tree can be seen and the rest is hidden by the building. The building is 12 metres high. What is the height of the tree?

If 2/5 of the tree can be seen the tree covers ( 1 - 2/5) 3/5 of the tree. If the  building is 12 metres high, it means that 2/5 of the building is 12m high

the height of the tree = 12 x (5/2) = 30m

Identify the area of the composite shape.
71 cm squared
98 cm squared
34 cm squared
56 cm squared

Answers

Answer:

Option (1)

Step-by-step explanation:

Area of the composite figure ABCDEFGH = Area of rectangle ABGH - Area of rectangle CDEF

Area of rectangle ABGH = Length × Width

                                         = 14 × 7

                                         = 98 cm²

Area of rectangle CDEF = 9 × (7 - 4)

                                        = 27 cm²

Area of the composite figure = 98 - 27

                                                = 71 cm²

Option (1) is the correct option.

Two
angles, ZJ and ZK are supplementary. The measure of ZJ is (2x+5)°. The
measure of ZK is (3x-10)°. What is the measure of ZK?

Answers

Answer:

ZK = 95 degrees

Step-by-step explanation:

Supplementary angles are when the sum of 2 angles equals 180 degrees. Since ZJ and ZK are supplementary, we can add both of them to equal 180 degrees.

ZJ + ZK = 180

Our first objective: find the value of x

(2x + 5) + (3x - 10) = 180

2x + 5 + 3x - 10 = 180

Combine like terms

5x - 5 = 180

Add 5 to both sides to isolate variable x

5x = 175

Divide both sides by 5 to isolate variable x

x = 35

Plug in x value for ZK expression
