Answer:
64 degrees
Step-by-step explanation:
Lets find the measure of the other angle in the other triangle with measures of 84 and 36.
Since there are 180 degrees in a triangle, we just add the other two angles and subtract from 180:
84 + 36 = 120
180 - 120 = 60
So the measure of the other angle in the other triangle is 60. Since there is a right angle we subtract 60 from 90
90 - 60 = 30
So the triangle with the missing angle has two angles with measures of 86 and 30. Now we add the measures and subtract from 180 again.
86 + 30 = 116
180 - 116 = 64
So the missing angle has a measure of 64 degrees
Answer:
64°
Step-by-step explanation:
all triangles equal 180°
so the first triangle with two angles already know is..
36+84+?=180
120+?=180
180-120=60°
but as you can see when they connect to each other they form 90°
so to find that angle on its own it's (with the triangle with one angle found) it's..
90-60=30°
and as we know all triangles equal 180°, so..
86+30+?=180
116+?=180
180-116=64°

Answer:
25
Step-by-step explanation:
180-90-65 = 25
Opposite angles are same
Step-by-step explanation:
app it's a standard 30 60 90 triangle. there are rules for this.
x = 3
y = 6
Area=1/2 times bas time height
given that area=10
height=5
find base
10=1/2 times base times 5
times 2 both siddes
20=base times 5
divide oth sides by 5
4=base
the base is 4m
2bc
=2(2)(3)
=4(3)
=12
2bc = 12
b=2
c=3
