9514 1404 393

Answer:

  ∠4 = 100°

Step-by-step explanation:

This has nothing to do with parallel lines.

Angles 1 and 4 are "vertical angles", hence congruent.

  ∠1 = ∠4 = 100°

_____

Vertical angles are on opposites sides of the intersection where lines cross.

Harry invests £6000 in a savings account.
zysi [14]

Step-by-step explanation:

here,

principal (p)=£6000

Rate (R)=. 3.4%

time (t)=3 yrs

now,

total investment is compound amount i.e CA

here,

CA = p(1  + \frac{r}{100} ) ^{t}

=£6000(1+3.4/100)^3

=£6633.044

here he will get his total investment as £6633.044 in compound interest of 3.4%

Given: ΔАВС, m∠ACB = 90°,m∠ACD = 30°,AD = 8 cm. Find: CD, Perimeter ΔABC <br><br> Please solve!
sukhopar [10]
If m ACD = 30 => m DCB = 60.
In triangle ACD:
sin 30^{o}=sin  \frac{AD}{AC} =\ \textgreater \   \frac{1}{2}  =  \frac{8}{AC} =\ \textgreater \  AC=16&#10;
CD= 8 \sqrt{3}
BC= 16\sqrt{3}
AC^{2}+CB^{2}=AB^{2} => AB=\sqrt{1024}=32.
=> P=16+32+16 \sqrt{3}=48 +16 \sqrt{3}.
