Answer:
<em>The measure of the angles is 45° and 135°</em>
Step-by-step explanation:
When two lines intersect, a linear pair of angles is formed. Two angles are said to be linear if they are adjacent, so a linear pair of angles must add up to 180 degrees.
Let's call x and y the two required angles. Knowing they form a linear pair:
x+y=180
We also know one angle is 1/3 of the other angle, thus:
x=y/3
Or, equivalently:
3x=y
Substituting y into the first equation:
x+3x=180
Simplifying:
4x=180
Solving:
x=180/4=45
The other angle is:
y=3x=3\cdot 45=135
Thus the measure of the angles is 45° and 135°
This is my first time on this app but this question doesn’t look to hard i’m ok at math but not that good at showing my work
Isosceles triangles have to equal sides
and each side is 5 cm greater than the base
you know the perimeter is 46
i would use basic algebra
x = base
46 = 2(x +5) + x
the 2(x +5) is the equal sides
46 = 2(x+5) + x
using distributive property
46 = 2x + 10 + x
add the common variable
46 = 3x + 10
now it’s easy
3x = 46 - 10
3x = 36
x = 36 / 3
x = 12
now that we got x (base)
we know that the equal sides are 5 cm longer than the base
12 + 5 = 17
since there are 2 sides and they are equal they are both 17
so each side of the triangle would be
1. 17 cm
2. 17 cm
3. 12 cm
to check you should be able to add them all together and get 46
17 + 17 + 12 = 46
Answer:
x = 15
Step-by-step explanation:
x + 2 = 17
We can subtract 2 from both sides:
x + 2 - 2 = 17 - 2
x = 15
Answer: x = 15
