£10+£5 = £15
£15-£1 = £14
he has spent £14.
so...........
14 divided by 10 = 1.4
1 packet of card costs £1.40
hope it helped :)
Answer:
x = 70°
Step-by-step explanation:
The relevant relations are ...
- base angles of an isosceles triangle are congruent
- consecutive interior angles where parallel lines meet a transversal are supplementary
__
Triangle OBQ is isosceles, so angle OQB = 40°. Triangle OPQ is isosceles, so angle OQP is x. The sum of angles OQB and OQP is angle BQP, which is supplementary to angle OPQ. That is, ...
(40° +x) +x = 180°
2x = 140° . . . . . . subtract 40°
x = 70° . . . . . . divide by 2
_____
There are many ways to find x. The one shown here is just one of them. In general, right triangles, isosceles triangles, symmetry, inscribed angles can all be used to write relations involving the known angles and x.
The slope of the line containing the points (2,3) and (9,7) is 4/7.
Slope Formula: y₂ - y₁ 7 - 3 4
------------- = ----------- = -------
x₂ - x₁ 9 - 2 7
4/7 can't be reduced any further, so that's your final answer.
