Step-by-step explanation:
at first give expression .
Answer:
50°
Step-by-step explanation:
x+15+2x=90
3x=90-15=75
x=75/3=25
one acute angle=25+15=40°
other acute angle=2×25=50°
<span>An upper quartile is the range of numbers above the median in a set. Thus, the numbers have to be rearranged mentally or on paper. Fortunately, there are an odd set of numbers, so one number, 25, is the median. The upper quartile is 30, 35, 40, 45.</span>
2x + y = 0
2x + 3 = 0
- 3 - 3
2x = -3
2 2
x = -1¹/₂
(x, y) = (-1¹/₂, 3)
Answer:
hey,its option a
Step-by-step explanation:
because angle F= angle M and angle G= angle L
and angle H= angle N
To know third angle in ∆HGF
,we know sum of all angles in a triangle is 180°
______________________________
let angle H be unknown value x
x+51+36=180
x=180-87 ---------------- 1
similarly in ∆MNL
let angle be y
51+36+y=180
y=180-87----------------2
_______________________________
From 1&2 we observe qngle x= angle y
