I'm pretty sure it is C. 45 because compass and straightedge is a right angle or an acute angle and 45 is less than a right angle
Y= x-4: gradient is 1 ; y- intercept is -4
g= -3+6
g= 3: y-intercept is 3; gradient is 0
Then you graph it
After graphing it you should find the intersection of this two line which I marked on the graph.
I’m not sure if the question is just asking you to show how these two functions are expressed on a graph or does it actually ask you to find the intersection of the two lines
But yea the coordinates of the intersection is (7,3)
Answer:9*(n+4)
Step-by-step explanation:
Product means multiply
sum means add
We do the sum first
Let n be the unknown number
sum of a number and 4.
(n+4)
now do the product
9*(n+4)
X+2x+5x=180
8x=180
4x=90
x=90/4
x=22,5
the angles are 22,5, 45, 112,5
x+2x+3x=180
6x=180
x=180:6
x=30
the angles are 30,60, 90
Are you sure the ex is correct???
