Anyone i need help with this
DIA [1.3K]

Answer:

Step-by-step explanation:

a1=90-a2

a1=90-30=60

a2 is opposite 30 and opposite angles are equal so

a2=30

The sum of the angles of a triangle are equal to 180 degrees.

a2+a3+70=180

a3+30+70=180

a3=100=180

a3=80

What value of m makes the system of linear equations mx − y + 3 = 0, (2m − 1)x − y + 4 = 0 have no solution?
Morgarella [4.7K]

Answer:

m ≠1  ( all m in R  except 1 )

Step-by-step explanation:

hello :

mx − y + 3 = 0.....(*)

(2m − 1)x − y + 4 = 0 ....(**)

multiply (*) by : -1       you have :   -mx+y-3=0   ....(***)

                                                    (2m − 1)x − y + 4 = 0 ....(**)

add(***) and(**)  : -mx+ (2m − 1)x+1 =0

(2m-m-1)x+1=0

(m-1)x = -1

this system have no solution  if : m-1≠0   means : m ≠1

#17. The height, H metres, of a certain species of Fir
olya-2409 [2.1K]

Answer:

The approximated height of the tree is of 112 meters.

Step-by-step explanation:

The height of a tree with a base diameter of d meters is approximated by the following formula:

h = 35d

In this question:

Base diameter of 3.2m, so d = 3.2, and the height is in meters.

h = 35d = 35(3.2) = 112

The approximated height of the tree is of 112 meters.

11m + 13 = m + 23

<u>Get m by itself by subtracting m from both sides. </u>

10m + 13 = 23

<u>Subtract 13 from both sides.</u>

10m = 10
