How can I solve these problems
2 answers:
For the first 6 problems you need to know that all the angles in a triangle are equal to 180°.
for example: #1
60 + 75 + x = 180
x = 180 - (60 + 75)
x = 180 - 135
x = 45°
for numbers 7 and 8, you just need to know that vertical angles are equal to each other.
for example: #7
3x = 45°
x = 45 ÷ 3
x = 15°
for number 9, you need to know that those to angles add up to give you 180° because lines are 180°.
for example: #9
5x + 12 + 68 = 180°
5x + 80 = 180
5x = 180 - 80
5x = 100
x = 100 ÷ 5
x = 20°
I really hope that this made sense to you and that this actually helped you.
Answer:
Step-by-step explanation:
Easy the three angles of a triangle equal 180 degrees
so 60+75 = 135 --> 180-135=
1) 145
2) 35
3) no since the tops a 100 and its a Isosceles triangle two corners left it be 40 for each corner
4) 34 for both x's cause 34+34+112. = 180
5) 180- 120= 60- 10 = 50/4 is (12.5)= x
6) x = 15 cause it be 120- 60 to get 60

Answer:
10 / 12
simplified:
5/6
since 5 is a prime number, we can't simplify this ratio any further
Tangent Θ = opposite / adjacent
AB = short leg = opposite = 12
AC = long leg = adjacent = 5
BC = hypotenuse = 13
tangent Θ = 12/5 ⇒⇒⇒ this is in ratio form
tanΘ = 2.4 ⇒⇒⇒ this is in decimal form
I think its 2.8.
Reason why:
4/5 = 0.8
Then the 2 would a whole number...
so 2.8.
Answer: y>(1/3)x-3
Step-by-step explanation: The slope is 1/3. The dotted line means it is not inclusive, and the value of k means it is going down three units.
